A dead arm rarely announces itself with a grimace on the mound. Sometimes the warning comes from a fastball that no longer has its usual life. Other times, it comes from the thunderous crack of a bat.
On October 17, 2024, Emmanuel Clase stood on the mound at Progressive Field, watching Giancarlo Stanton’s home run disappear into the Cleveland night. Aaron Judge had already taken him deep. Two swings had erased the Guardians’ eighth-inning lead in Game 3 of the American League Championship Series.
Cleveland somehow survived, winning 7–5 in ten innings. Hours later, manager Stephen Vogt faced an uncomfortable question. Could he ask baseball’s most dominant regular-season closer to handle another desperate ninth inning?
He did. Clase returned the following night and surrendered two more go-ahead runs. Meanwhile, rookie Cade Smith, another cornerstone of Cleveland’s bullpen, had experienced his own alarming decline.
Back-to-back high-leverage relief appearances were supposed to be Cleveland’s postseason advantage. Suddenly, they looked like the very thing threatening its season.
The question wasn’t whether these pitchers possessed enough talent. Their regular-season numbers had answered that. The harder question concerned how much October baseball could extract from their arms before something finally gave.
Cleveland’s 2024 Bullpen Carried More Than Its Share
The Guardians arrived in October with a bullpen capable of shortening games. Smith, Tim Herrin, Hunter Gaddis, and Clase formed a formidable late-inning group. Give Cleveland a narrow lead after six innings, and opponents faced an exhausting succession of power arms.
Their effectiveness helped cover a battered starting rotation.
Shane Bieber had undergone Tommy John surgery in April, while Gavin Williams lost significant time to an elbow injury earlier in the season. Matthew Boyd returned from his own Tommy John recovery in August, and veteran Alex Cobb battled several physical setbacks.
Cobb then suffered a back strain during ALCS Game 1, forcing Cleveland to replace him on the roster. Vogt had fewer dependable starting options and little patience for letting a shaky outing deteriorate.
The bullpen became his answer.
According to MLB’s October 19, 2024, reporting, Cleveland’s relievers had thrown 49⅓ innings through nine postseason games. The starters managed just 29⅔ innings.
That meant the bullpen covered nearly 62.5% of the team’s pitching workload during those games.
Smith and Herrin appeared in eight of Cleveland’s first nine playoff contests. Both established a franchise record for appearances over that opening postseason stretch.
The arrangement looked sustainable while the fastballs kept exploding through the strike zone. Then the Yankees exposed how little room Vogt had left for error.
Cade Smith Lost Two Miles Per Hour When Cleveland Needed Him Most
On October 17, Smith carved through Juan Soto, Aaron Judge, and Giancarlo Stanton in Game 3. Ten pitches. Ten strikes. Three outs against the most dangerous portion of New York’s lineup.
His fastball looked untouchable.
The following evening, those same hitters returned with a different result. Smith walked Soto to begin the sixth inning, surrendered a single to Judge, and eventually faced Stanton with two runners aboard.
Stanton crushed a 1-2 fastball for a three-run homer. New York’s advantage swelled to 6–2.
More revealing than the result was the radar gun.
MLB’s postgame analysis showed Smith’s four-seam fastball averaged 94.0 mph in Game 4, down from his combined regular-season and postseason average of 96.0 mph entering that night.
For a pitcher whose fastball had dominated hitters throughout the season, that decline mattered.
Vogt acknowledged the physical reality afterward, saying, “Everybody is tired.” He also suggested Smith had shown some fatigue, though the manager credited New York’s hitters for their approach.
Smith offered a different explanation. He believed his command had deserted him and that he had given Stanton exactly the pitch the slugger wanted.
Both observations could coexist.
You can’t blame every poorly located fastball on exhaustion. Sometimes a dangerous hitter simply wins the confrontation. A pitcher operating below his usual physical sharpness has less margin when his delivery slips.
Back-to-back relief appearances had transformed Smith’s margin from comfortable to razor-thin.
Clase’s Final Innings Revealed Vogt’s Impossible Choice
Clase entered the 2024 postseason with a staggering résumé. MLB’s official records credited him with 47 saves and a 0.61 ERA during the regular season.
He had surrendered just five earned runs across 74⅓ innings.
Then October changed the equation.
Judge and Stanton homered against him in Game 3. Cleveland still won, but the Yankees had demonstrated that Clase’s devastating arsenal could be beaten.
In Game 4, Vogt summoned him again with the score tied in the ninth. New York scored twice and escaped with an 8–6 victory.
On October 19, facing elimination in Game 5, Cleveland returned to its closer.
This time, Clase looked like himself. He struck out Stanton with a 100.6 mph pitch, leaned heavily on his cutter, and completed a scoreless ninth.
Of his 12 pitches, 11 were cutters averaging 100 mph, according to MLB’s game report.
The performance seemed to invite another inning. Instead, Vogt sent Hunter Gaddis out for the tenth.
His explanation revealed the physical calculation behind the decision: Clase had already thrown 60 pitches over three days.
Gaddis nearly escaped the inning. Brayan Rocchio failed to secure Andrés Giménez’s throw at second base on a potential double-play ball, keeping New York’s threat alive.
Juan Soto eventually punished Cleveland with a three-run homer, sending the Yankees to the World Series.
The Guardians’ season ended 5–2 in ten innings.
Clase had finally rediscovered his command, but Vogt could not reasonably ask him to carry another full inning. Cleveland’s best weapon remained available in theory. In practice, his workload had narrowed the manager’s choices.
The Physical Workload That Never Appears in a Box Score
A box score might show that a reliever threw 15 pitches. What it won’t show is how many times he got loose, how hard he threw before entering, or whether he warmed up for an appearance that never happened.
Consider an October bullpen during the seventh inning.
A right-hander begins stretching as the opposing team’s cleanup hitter approaches. He makes several easy throws, gradually increases the intensity, and starts snapping breaking balls toward his catcher.
Then his team’s offense scores twice.
The manager changes his plan. Nobody calls for the reliever, but the pitches he threw to get ready still count toward his physical activity.
Next inning, the process might begin again.
That’s the invisible side of back-to-back high-leverage relief appearances.
A 2023 study published in the Orthopaedic Journal of Sports Medicine examined pitching workloads for 137 players within one MLB organization during the 2021 season.
The researchers tracked official pitches alongside warmups and other throws that traditional game statistics overlook.
Their findings were striking: 45.4% of the pitchers’ total recorded throws came from these hidden pitches, on average.
The study did not find that pitchers with higher hidden-pitch workloads suffered significantly more injuries. Still, it demonstrated how much throwing conventional box scores leave uncounted.
Those extra throws become especially relevant in October, when managers repeatedly prepare their best relievers for emergencies that may never arrive.
A pitcher can leave the stadium without an official appearance and still wake up having completed a meaningful throwing session.
What a Tired Delivery Actually Looks Like
Fatigue rarely produces one unmistakable mechanical defect. Instead, a pitcher may struggle to repeat movements that normally feel automatic.
His arm slot might drop slightly. The front shoulder could open too early, pulling his throwing arm through a different path. A tired lower half may produce less drive toward home plate.
These changes can show up in several ways.
A fastball intended for the outside corner leaks across the middle. Another sails high and arm-side. The slider that usually disappears beneath a hitter’s barrel stays elevated long enough to invite contact.
Coaches can investigate those changes using Baseball Savant’s pitch-tracking data, including release points, velocity, movement, and location.
In Smith’s 2024 ALCS outing, the velocity decline provided a measurable warning. It did not identify which part of his mechanics had changed, but it gave Cleveland something more concrete than a vague impression of tiredness.
For relief pitchers, even small inconsistencies can become expensive.
Starters sometimes have several innings to adjust when their command disappears. A reliever entering with two runners aboard might have only three pitches before the damage becomes irreversible.
Back-to-back relief appearances reduce the recovery time available to correct those problems before the next assignment.
What Sports Medicine Reveals About Consecutive Pitching Days
The human elbow doesn’t distinguish between a playoff pitch and a meaningless September delivery. Both place stress on the structures supporting the throwing arm.
The ulnar collateral ligament helps stabilize the inside of the elbow. Meanwhile, the forearm’s flexor-pronator muscles contribute additional support as the pitcher accelerates toward release.
Repeated throwing can temporarily alter how those structures respond to stress.
In August 2026, researchers published a study in the Orthopaedic Journal of Sports Medicine examining 26 high school baseball pitchers after 100-pitch sessions.
Doctors measured changes around the elbow immediately after throwing and at several intervals over the following 24 hours.
The findings showed temporary reductions in elbow stability after pitching. Several measured indicators returned toward their prethrowing levels within 18 to 24 hours.
The study involved teenage pitchers throwing one controlled session. It cannot establish how quickly an MLB reliever recovers from consecutive maximum-effort outings.
The practical lesson is narrower, but useful. Recovery involves more than whether a pitcher wakes up without soreness.
Adrenaline Can Make an Exhausted Arm Feel Ready
October adds another complication: adrenaline.
The crowd rises as the bullpen door opens. A reliever crosses the warning track, hears his entrance music, and starts preparing for a confrontation that could decide the pennant.
In that moment, physical discomfort may feel secondary to the competition.
Adrenaline can sharpen alertness and change an athlete’s perception of exertion. The sensation of readiness doesn’t guarantee that every muscle and stabilizing structure has fully recovered.
Pitchers understand the consequences of admitting they need additional rest. They also know another reliever might surrender the lead they believe they can protect.
The manager and training staff must weigh more than a player’s willingness to take the ball.
Workload history, throwing intensity, mechanical consistency, and recovery all deserve attention.
The challenge grows when back-to-back high-leverage relief appearances become three outings in four days, followed by another must-win game.
The 2026 ALCS Has Brought Cleveland Back to the Same Crossroads
Two Octobers after the Yankees battered Cleveland’s bullpen, Vogt is managing another American League Championship Series. This time, the Tampa Bay Rays stand between the Guardians and the World Series.
The personnel has changed, but the central question remains familiar.
Cade Smith, Cleveland’s devastating setup weapon in 2024, now occupies the closer’s role. His 2026 regular season produced 41 saves, 107 strikeouts, and a 1.95 ERA over 74 innings.
Vogt has leaned on him repeatedly.
MLB reported on October 14 that Smith had appeared in 18 of Cleveland’s previous 20 postseason games, an unprecedented workload over that particular span.
Three days later, the Guardians faced another bullpen management problem.
A Rainout Turned the Schedule Into Four Straight Games
Heavy rain postponed Game 4 of the Cleveland-Tampa Bay series from Friday, October 16, to Saturday, October 17.
The revised schedule eliminated Sunday’s planned off-day.
Suddenly, Cleveland faced the possibility of four consecutive games from October 17 through October 20, including a potential Game 7.
Vogt maintained his plan to use Shawn Armstrong as the opener for Game 4. The decision reflected a deliberate attempt to preserve other starting options, even as the compressed calendar threatened the bullpen’s recovery windows.
Cleveland lost that game 7–3.
The seventh inning brought a defensive mistake reminiscent of 2024. Chase DeLauter failed to handle Jonathan Aranda’s ground-ball single in right field, helping Tampa Bay build a commanding advantage.
Vogt had kept Smith, Gaddis, and Erik Sabrowski out of the defeat. All three were therefore available for Game 5.
That decision illustrated a different side of postseason bullpen management. Sometimes protecting the best arms means accepting a difficult matchup today to preserve a stronger combination tomorrow.
The plan still required the starting pitcher to provide enough innings.
On October 18, rookie Parker Messick lasted just two innings against Tampa Bay. He threw 57 pitches, allowed two runs, and left Cleveland searching for seven more innings.
The Guardians used Armstrong, Sabrowski, Gaddis, and Smith in relief, but their offense could not solve Drew Rasmussen. Tampa Bay won 3–1 and seized a 3–2 series lead.
Now Cleveland heads to Game 6 on October 19 facing elimination.
Vogt Faces an Even More Familiar Question About Cade Smith
The difference between 2024 and 2026 is that Smith has become the man Vogt trusts to finish games.
During this postseason, the closer has embraced the responsibility. Against Tampa Bay in Game 3, he recorded a four-out save in Cleveland’s 3–2 victory.
Smith struck out Yandy Díaz on a 98 mph fastball after a ten-pitch battle. He returned for the ninth and retired the next three hitters to finish the game.
According to MLB, he had appeared in 19 of Cleveland’s 21 postseason games since 2024 at that point.
The workload has not prevented Smith from delivering dominant outings. It leaves Vogt with a recurring decision about when to use his closer and how much recovery he needs.
Back-to-back relief appearances become particularly difficult to manage when the next game could end the season.
The Guardians cannot preserve Smith indefinitely. They also cannot assume his effectiveness will survive unlimited use.
Vogt has already experienced what happens when the two priorities collide.
How October Managers Can Protect Their Best Relievers
Every playoff manager wants his best arm facing the opponent’s most dangerous hitter. The problem is that the most important confrontation doesn’t always arrive in the ninth inning.
Consider a seventh-inning situation with two runners aboard and the middle of the lineup approaching.
The manager can summon his closer early, risking another extended outing. Alternatively, he can trust a less dominant pitcher and save the closer for a lead that might disappear.
Neither decision guarantees safety.
The smarter approach begins with understanding each pitcher’s actual workload, not simply his official appearances.
A reliever who needed several intense warmups yesterday may require a different recovery plan than someone who completed one quick inning without additional preparation.
Teams can also examine changes in release point, fastball velocity, and pitch movement. Those measurements won’t diagnose exhaustion by themselves, but they can identify departures from a pitcher’s usual delivery.
Communication matters just as much.
A pitching coach who notices an inconsistent arm slot can intervene before the problem grows. Meanwhile, the training staff can compare recovery information with the pitcher’s established workload.
The objective isn’t to eliminate back-to-back high-leverage relief appearances. Postseason baseball will always demand them.
Teams must recognize when another inning offers diminishing returns and when a fresh arm presents the better option.
The Next October Test Will Come Down to One More Inning
The lessons from Cleveland’s 2024 collapse have returned at an uncomfortable moment.
Back-to-back high-leverage relief appearances helped carry the Guardians deep into that postseason. Those same pitchers eventually encountered a Yankees lineup that punished every mistake.
Two years later, Cleveland faces Tampa Bay with its pennant hopes again resting partly on a handful of trusted arms.
The difference is that Vogt now has direct experience with the consequences of relentless bullpen usage.
He watched Smith’s fastball lose two miles per hour against New York. He saw Clase surrender decisive runs on consecutive nights, then recover just as his workload forced an impossible choice.
Those memories do not mean every tired pitcher will collapse. Some relievers respond beautifully to repeated appearances, particularly when their workloads remain manageable.
Consecutive outings carry physical demands that cannot be measured through innings alone.
A manager must decide how much trust to place in yesterday’s dominance. The pitcher must determine whether his body can reproduce the same delivery when the bullpen phone rings again.
And the hitter standing 60 feet, six inches away doesn’t care how many throws preceded the confrontation.
As the 2026 ALCS moves toward its conclusion, Smith and Cleveland’s bullpen may again face those decisions with an entire season at stake.
There will be no convenient pause to measure every hidden pitch or evaluate every subtle mechanical change.
Vogt will have to make his choice while the stadium roars and the next batter approach the plate.
Back-to-back relief appearances represent one of October baseball’s hardest physical bargains. They ask extraordinary athletes to repeat their most demanding work before their bodies have had enough time to recover. Sometimes that gamble produces a strikeout that sends the stadium roaring. Other nights, one fastball hangs over the plate just long enough to end a season. And when the bullpen phone rings again, every manager faces the same brutal question: How far can he push the arm that carried his team this close to glory before one more inning becomes one inning too many?

FAQs
Q1. Why do relief pitchers struggle with back-to-back playoff appearances?
Short recovery windows, repeated warmups, and high-intensity pitches can affect velocity and command. Even elite relievers sometimes struggle to maintain their usual precision.
Q2. What are hidden pitches in baseball?
Hidden pitches include bullpen warmups and throws between innings. Official game pitch counts don’t include them, even though they add to a pitcher’s workload.
Q3. How much did Cleveland’s bullpen pitch during the 2024 playoffs?
Through nine postseason games, Cleveland’s relievers threw 49⅓ innings. The starting rotation contributed just 29⅔ innings.
Q4. Why didn’t Stephen Vogt use Emmanuel Clase in the tenth inning of ALCS Game 5?
Clase had already thrown 60 pitches over three days. Vogt chose Hunter Gaddis rather than extend his closer’s workload further.
Q5. How did the 2026 ALCS rainout affect Cleveland’s bullpen?
The postponement removed a scheduled off-day and compressed the series. Vogt faced more difficult decisions about keeping his relievers fresh.
