MLB hitting prospects can make the future sound certain with one crack of the bat. In February 2025, Jac Caglianone launched a spring-training homer that traveled 435 feet at 115.4 mph, according to MLB’s game coverage. The ball supplied the spectacle; the tracking equipment confirmed the force behind it.
Nobody needed another swing to establish that Caglianone could punish a baseball. The harder question concerned which pitches would let him do it again. A replay cannot show how a hitter will respond when opponents stop offering the pitch he wants.
That gap separates an impressive reading from a complete evaluation. A prospect might crush a mistake over the plate, then chase a slider beyond his reach. Another might never match that peak but keep driving hittable pitches into the gaps.
For scouts and player-development staffs, the work starts where the highlight stops. Exit velocity tells them how fast the ball left the bat. The next step requires following the entire plate appearance, including the swings that never touch anything.
Read the contact before judging the hitter
Watch a hard grounder skip toward the shortstop. The infielder gathers it, plants, and throws across the diamond. However, the velocity reading might look more impressive than the routine out suggests. Exit velocity measures speed at contact, not the value of the resulting play. When evaluating MLB hitting prospects, start by separating a hitter’s hardest ball from his usual contact.
Maximum exit velocity records the best reading in the sample. Average exit velocity includes the topped grounders and jammed flares surrounding it. A hitter can own an extraordinary maximum without regularly approaching it.
Hard-hit rate adds frequency to the picture. MLB’s Statcast system classifies contact at 95 mph or above as hard-hit, then calculates its share of tracked batted balls. That gives evaluators a way to distinguish occasional explosions from repeated force.
However, none of those measures tells the whole story of where the ball travels. Statcast’s barrel classification combines speed with launch angle, requiring at least 98 mph and a suitable trajectory. A hitter must do more than swing hard to meet that standard.
The most consequential omission comes before contact. Strikeouts never enter the average exit-velocity calculation. A player’s best swings can therefore look healthy while too many of his plate appearances end in the catcher’s glove.
Roman Anthony made the hard contact repeat
The appeal of Roman Anthony’s 2025 major league contact record extends beyond any single ball disappearing into the outfield. According to Baseball Savant tracking data, he averaged 94.5 mph across 174 batted balls, with a 60.3% hard-hit rate and 27 barrels. Those measurements captured repeated damage rather than one exceptional swing.
For MLB hitting prospects, that combination gives the power projection substance. Anthony’s average showed how firmly he struck the ball overall. His hard-hit rate showed frequency, while the barrels identified contact that paired force with productive elevation.
No single Anthony number should become an entrance requirement for other young hitters. Different players can build useful offensive profiles through different combinations of contact, patience, and power. However, anyone projecting a similarly dangerous bat should look for evidence that survives beyond the highlight reel.
The next step takes the evaluator back to the pitches themselves. Does the hitter drive fastballs in more than one location? Can he punish a breaking ball that hangs without chasing the one that finishes below the zone?
Those questions keep the data connected to baseball. A strong average identifies something worth investigating; video helps establish how the player produces it. The scouting report becomes more useful when it explains which swings create the numbers.
Caglianone had the force but needed the flight
Caglianone’s spring homer established the strength in his swing. His subsequent 2025 major league contact record showed how much work remained in putting that strength to use.
According to Baseball Savant, Caglianone reached 114.1 mph in major league play that season, yet MLB’s subsequent analysis reported a 50.6% ground-ball rate. More than half his batted balls stayed on the ground. That left a clear gap between his raw power and its application: he could overwhelm a pitch without producing a flight that threatened the fence. A hard two-hopper might hurry the shortstop, but it still gives him a play.
For MLB hitting prospects with that profile, the coaching question should begin with the pitches that produced those grounders. Did the hitter catch a hittable fastball too far forward? Was he reaching for a pitch he should have left alone?
The aggregate numbers cannot answer either question. Evaluators need the individual batted balls and the swings behind them before recommending a change.
Simply demanding more loft skips that work. A useful adjustment should help the hitter drive an appropriate pitch without making other pitches harder to handle. Otherwise, a prettier flight on contact could come with more empty swings.
Caglianone also produced 19 barrels across 158 batted balls in 2025, according to Baseball Savant. Those swings gave coaches successful contact to examine alongside the grounders. The task was to identify what allowed those swings to work and whether he could repeat it more often.
Coby Mayo exposes the missing part of the chart
An exit-velocity leaderboard has no entry for a bat passing over a slider. Coby Mayo’s difficult 2024 introduction to the majors shows why those missing swings deserve attention.
According to Baseball Savant’s batting records, Mayo made 46 plate appearances across 17 games and struck out 22 times. That produced his 47.8% strikeout rate. He put just 19 balls into play, averaging 84.7 mph on that contact.
The small sample demands restraint. Seventeen games cannot settle a young hitter’s future, and 19 batted balls offer little room for a stable assessment. However, the strikeouts clearly limited how often Mayo could bring his power into those games.
This creates a different evaluation problem from Caglianone’s uneven ball flight. Before asking how much damage a hitter does on contact, establish whether he makes enough contact to sustain the projection.
For MLB hitting prospects, the diagnosis must go beyond labeling someone a swing-and-miss risk. A late swing against a high fastball and an early commitment against a changeup require different explanations. Chase rate, contact rate, pitch location, and video can help separate them.
The numbers should direct that investigation. They should not encourage a coach to rebuild a swing merely because a short stretch produced ugly results.
Compare the assignment as well as the reading
A fastball over the middle gives the hitter a different assignment from one at the upper edge. Both can produce the same exit velocity, but the swings may reveal different strengths.
Comparisons among MLB hitting prospects should therefore identify the competition level, measurement period, and number of tracked batted balls. A brief surge at one affiliate does not carry the same weight as sustained contact across a longer stretch. Mixing those samples makes a leaderboard easier to build and harder to trust.
Upper-end measures can help put a maximum in perspective. The 90th-percentile exit velocity marks a point near the top of a hitter’s contact distribution. Unlike a personal best, it draws attention to more than the single hardest ball.
However, it still needs a clearly defined sample. No percentile can repair missing information about which games or batted balls the comparison includes.
Improvement deserves the same scrutiny. If a hitter starts producing harder liners, check whether he also maintains his contact frequency. A stronger swing helps most when the player can keep finding pitches to use it against.
The next pitcher gets a scouting report too
The most revealing plate appearance might never become a highlight. A hitter takes a slider below the knees, fouls off a fastball, and drives the next pitch into the gap. The final reading captures only the last part of that work.
Evaluating MLB hitting prospects means accounting for the decisions that made the hard contact possible. Raw strength establishes what a hitter can do to the right pitch. Selection, timing, and contact frequency determine how often he gets to show it.
A useful evaluation follows that sequence. Establish the force, examine the flight, and count the opportunities lost to missed swings. Then return to the video and find the pitches that explain the pattern.
Patience matters, too. Mayo’s short introduction cautions against turning an early struggle into a permanent label. Anthony’s repeated hard contact offers firmer evidence, while Caglianone’s grounders identify a specific obstacle between strength and production.
For MLB hitting prospects, those distinctions carry more weight than another decimal place on a leaderboard. They tell a development staff what to investigate and give the player something more useful than instructions to swing harder.
Caglianone’s 115.4 mph spring blast answered the question of whether he could hit a ball with exceptional force. Across the mound, though, a pitcher has no obligation to supply that pitch again. The display can hold its number. In the batter’s box, the hitter must solve a new problem.

FAQs
What does exit velocity tell us about MLB hitting prospects?
Exit velocity measures how fast the ball leaves the bat. It reveals contact strength, but scouts also examine ball flight, pitch selection and missed swings.
What counts as a hard-hit ball in baseball?
MLB’s Statcast system counts a ball hit at 95 mph or faster as hard-hit.
Why can a powerful hitter still struggle?
A hitter can strike the ball hard but produce too many grounders or miss too many pitches. Raw strength alone cannot guarantee consistent offense.
What is the difference between maximum and average exit velocity?
Maximum exit velocity records a hitter’s hardest measured ball. Average exit velocity includes all tracked batted balls, including weak contact.
Why does sample size matter when evaluating prospects?
A few swings can distort a hitter’s numbers. Larger samples help evaluators judge whether strong contact repeats against comparable competition.
