The lights at Chase Field had settled into that familiar late-game glow when the night finally broke open. For seven innings, Brandon Pfaadt and Yoshinobu Yamamoto had traded zeros, each starter forcing hitters to work for every inch of the strike zone. Pfaadt had given Arizona seven scoreless innings. Yamamoto had gone 5⅔ without allowing a run, but his pitch count had climbed to 107. The game was still scoreless, yet the tension was beginning to feel heavier than the number on the scoreboard.
Then Kyle Tucker stepped in against Jonathan Loáisiga. The matchup itself reflected how different these 2026 rosters had become. Tucker was now wearing Dodger blue after signing with Los Angeles, while Loáisiga had become one of Arizona’s bullpen options. Tucker drove a 0-1 pitch over the right-field wall, and suddenly the Diamondbacks were three outs from falling behind. Los Angeles turned to Edwin Díaz, its new ninth-inning weapon, but the closer’s night quickly became complicated. Geraldo Perdomo and Corbin Carroll ripped consecutive triples, the lead vanished, and a game that had been controlled by starting pitchers became a test of bullpen nerve.
The Chase Field Thriller
For most of the night, the starting pitchers dictated the terms. Pfaadt attacked the Dodgers’ lineup without giving them many comfortable swings. His seven scoreless innings included only two hits and two walks, and both hits came from Andy Pages. Yamamoto matched that efficiency for much of his outing, working into the sixth before leaving with two runners aboard. Evan Phillips entered and stranded both, keeping the game locked at 0-0.
The stalemate finally ended in the eighth. Tucker came to the plate against Loáisiga and turned on a 0-1 pitch, sending it over the right-field wall. There was no extended rally, no sequence of bloop hits. One swing did it. The Dodgers had a 1-0 lead, and Arizona suddenly needed to find three outs against a lineup that had been quiet for most of the evening.
Los Angeles handed that lead to Díaz in the ninth. The first batter reached on a walk, and Perdomo followed with a triple that made the margin disappear. Carroll then lined another triple, bringing Perdomo home and putting the potential winning run just 90 feet away. The entire complexion of the inning had changed in two at-bats.
Díaz did not let the inning completely unravel. He struck out Ildemaro Vargas with the go-ahead run still at third, sending the game into extras. Ohtani then delivered the answer in the 10th, lining a two-out RBI single to put Los Angeles back in front. Jack Dreyer finished the job in the bottom half by starting a game-ending double play. The Dodgers walked away 2-1 winners and ended a seven-game losing streak.
Díaz and the Cost of Trust
Díaz’s ninth inning was difficult to separate from the night before. He had already blown a save against Arizona on Friday, when Ryan Waldschmidt’s walk-off two-run homer gave the Diamondbacks a 4-3 victory. The loss extended Los Angeles’ skid to seven games. Now, one night later, Díaz was back in exactly the situation a closer wants: three outs from protecting a one-run lead.
Instead, the first batter reached, Perdomo found the gap and Carroll followed with another triple. The Dodgers had watched a one-run cushion disappear before Díaz had recorded an out. That put manager Dave Roberts in a difficult position, but there was no immediate move to the bullpen. Díaz stayed on the mound.
The decision mattered because Arizona was one clean contact away from winning. Vargas came up with the winning run at third, but Díaz got the strikeout he needed. It was not a clean save, and the blown save remained on his line. Still, the closer had prevented the inning from becoming a second straight walk-off disaster.
The work before Díaz also shaped the decision. Los Angeles had already asked Alex Vesia and Tanner Scott to navigate difficult spots, with Scott escaping a bases-loaded jam in the eighth. Both teams were managing more than the inning in front of them. The previous night’s workload, the next day’s schedule and the condition of every available reliever were part of the calculation.
Arizona’s Counter-Formula
Arizona had spent most of the opener building the kind of game a bullpen prefers to inherit. Pfaadt went seven innings and gave up almost nothing. He had returned to the rotation on June 30 and entered this start having gone 6-1 with a 1.32 ERA over his previous eight outings. His recent form gave Lovullo every reason to let him work deep into the game.
That mattered because every inning from a starter is one fewer inning a manager has to assemble with relievers. Pfaadt did not need a seventh-inning bridge or an emergency eighth-inning arrangement. He simply kept pitching until the game reached its final stages.
Loáisiga entered in the eighth with that foundation behind him. Tucker’s home run changed the score, but not the entire game. The right-hander still recorded two strikeouts and kept the Diamondbacks within one run. When Perdomo and Carroll tied the game in the ninth, Arizona was still alive because the deficit had never grown.
The next afternoon showed the formula even more clearly. Eduardo Rodríguez threw seven innings, allowed two runs and struck out nine. Kevin Ginkel then handled the ninth with Arizona leading 4-2, retiring Los Angeles in order. Rodríguez’s 115-pitch outing meant Ginkel did not have to inherit a mess. He only had to finish one.
The Hidden Cost of Short Starts
That contrast was the real bullpen story of the weekend. Pfaadt and Rodríguez each supplied seven innings for Arizona. Yamamoto lasted 5⅔ in the opener, while Justin Wrobleski lasted only 3⅓ innings the following afternoon. The numbers left Los Angeles asking its relievers to absorb considerably more work.
Wrobleski’s short outing was especially costly. Arizona scored four runs, three against the Los Angeles starter, and Rodríguez remained on the mound long enough to push the Diamondbacks through seven innings. By the time Ginkel entered, Arizona had already done most of the difficult pitching work.
Bullpen fatigue rarely announces itself with one obvious moment. It appears gradually. A reliever used for six outs today may be unavailable tomorrow. A pitcher who normally handles the seventh may suddenly be asked to enter in the fifth. A closer can arrive in the ninth with a lead but without the ideal conditions that make a save routine.
For Roberts, that was the problem. His bullpen had to cover more innings while Arizona’s starters were protecting their relief corps. The difference did not necessarily show on the scoreboard until late, but it changed the choices available to each manager. Every additional out from a starter bought another option later.
A Rivalry of Tiny Margins
Saturday’s game was decided by almost microscopic differences. Pfaadt carried a shutout through seven. Tucker’s eighth-inning homer created a one-run lead. Perdomo and Carroll erased it in the ninth. Ohtani restored it in the 10th, and Dreyer’s double play ended the night. There was never a comfortable stretch for either bullpen once the starters departed.
The following game followed a different script. Arizona scored twice in the first and twice more in the second, then Rodríguez settled down and protected the advantage. Los Angeles got within two runs, but the Diamondbacks never had to turn the ninth into a crisis. Ginkel entered with a 4-2 lead and finished the game without allowing a baserunner.
That difference is why bullpen usage cannot be judged simply by the final three outs. A closer’s job becomes dramatically easier when the starter has already created a clean situation. Conversely, a bullpen can look vulnerable when it is repeatedly being asked to repair innings that began to unravel much earlier.
This rivalry has often been decided by those narrow margins. A single homer can overturn seven innings of work. One extra baserunner can force a manager to change the pitching plan. One additional inning from a starter can preserve an important arm for tomorrow. The decisions may happen quietly, but their consequences arrive loudly.
The Bigger Bullpen Picture
The weekend offered a useful snapshot of how the Dodgers and Diamondbacks approached late-game pressure. Arizona repeatedly benefited from starter length. Los Angeles had to ask more of its bullpen, particularly after Yamamoto and Wrobleski departed before the seventh inning. That difference gave Lovullo more flexibility and Roberts less room to improvise.
For Díaz, the ninth inning became the most dramatic example. He entered protecting a 1-0 lead, gave up the tying run, then found enough to keep Arizona from taking the lead. The following afternoon, the Dodgers were forced to cover most of the game with their bullpen after Wrobleski’s early exit. The workload was cumulative, even if no single number captured it.
Arizona’s advantage was easier to see. Pfaadt and Rodríguez each reached seven innings, allowing Lovullo to reserve his relievers for defined late-game assignments. Ginkel’s save was the cleanest expression of that advantage. He entered with a two-run cushion and needed only three outs.
The season eventually placed the weekend in a larger frame. Los Angeles finished with 100 wins, while Arizona went 86-76 and missed the postseason. Yet the games at Chase Field offered a smaller lesson that mattered long before those final records were written: bullpen performance begins with the innings that come before it.
That is what made the late drama so revealing. Tucker’s home run changed the score. Díaz’s ninth changed the mood. Ohtani’s single changed the result. But underneath those moments was the quieter contest of pitch counts, starter endurance, relief availability and managerial timing. In a rivalry this tight, the bullpen rarely gets to choose the conditions it inherits.
