Is It Legit? Geraldo Perdomo 2025 Performance Breakdown

As I work on my team-by-team top 30 prospect reports, I will start a new mini-series in between. As the team reports take some time to knock out, there is a need for some content in between. So, I figured a good solution would be breaking down MLB players that may be hard to rank.

These players might be recently graduated prospects who struggled. A former star or a random breakout. Are the performances legit, and what can we expect moving forward for 2026 and for dynasty leagues?

Today, we start with one of the biggest breakouts in 2026, Geraldo Perdomo. Posting a 7.1 fWAR with 20 home runs and 27 stolen bases, Perdomo looked like one of the best players in the game. Is it legit? Let’s break it down.

Geraldo Perdomo Breakdown: Was The Performance Legit?

The Numbers: Geraldo Perdomo Edition

Entering the 2025 season, Perdomo had spent three full seasons in a Diamondbacks uniform. He had a total of 14 career home runs across 1420 plate appearances with an OPS of .657. While Perdomo had steadily improved, no one expected the leap he made in 2025 as he ascended to star status.

Playing every day, Perdomo racked up 720 plate appearances and made the most of every one of them. He blasted 20 home runs, had 58 extra base hits, and a slash of .290/.389/.462. The 7.1 fWAR he posted was the fifth-highest in baseball, only behind stars like Aaron Judge, Cal Raleigh, Bobby Witt Jr., and Shohei Ohtani.

Driving in 100 runs and adding 98 RBI, only ten players had more combined runs and RBI, and Perdomo was incredibly consistent in those categories. Posting his highest sprint speed in several years, Perdomo’s sprint speed still ranked in the 45th percentile for all players. Despite that, Perdomo stole 27 bases and was only caught six times.

The strikeout rate was a career-low 11.5 percent, and Perdomo walked more often than that, checking in at a 13.1 percent clip. Almost every surface data point was a career best, so what does the underlying data suggest? Let’s take a look under the hood.

Checkin’ Under the Hood: Geraldo Perdomo

Let’s start with the worst underlying data, Perdomo, that belongs to Perdomo, and that is his bat speed. With an average bat speed of 68.3 mph, he ranked just in the seventh percentile among all MLB hitters. The positive is that in 2023, the number was 65.7 mph, and in 2024, it was 66.9, so we are looking at a three-year improvement. This largely affected his average exit velocity, which was below average at 87.6 mph, but that number was a career best. The hard-hit rate and barrel rate were also career-best marks, but still well below average at 31.9 percent and 6.2 percent, respectively.

So, how did Perdomo manage to hit 20 home runs given the low exit velocities? I mean, his 90th percentile exit velocity was well below average at 101.7 mph, and his max of 108.2 was very poor.

The home run power starts with angles. With a 36.2 percent sweet-spot rate, we see that Perdomo often finds ideal launch angles—the squared up rate of 32.3 percent ranked in the 92nd percentile for all MLB hitters. Pulling 20 percent of the balls he hits in the air, while also creating ideal angles, helps lead to the home runs. Therefore, I do not consider the 20 home runs to be fluky.

It may also make more sense when we see how often Perdomo puts the ball in play. We established that the strikeout rate was great and it ranked in the 95th percentile, but his 88 percent overall contact rate was 98th percentile: Aka, elite of the elite. The in-zone contact rate of 92 percent is also elite and aligns with what we saw from Perdomo in 2024.

Not only are the contact skills elite, but the approach is pretty stellar, too. The chase rate of 19 percent was identical to his career number. The only thing we could see improved is a zone-swing rate that is ten percentage points below the MLB average. The heart-swing rate is also a tad low at 70 percent, where the MLB average is 76 percent.

The final thing to take a look at is Perdomo’s splits as a switch-hitter. Spoiler alert: There are no holes to poke here. From the left side of the plate, Perdomo struck out just 6.8 percent of the time and slashed .341/.416/.486. From the right side, it is a slight step back, but still a strong .267/.378/.451 slash with an ideal walk and strikeout rate at 13.6 percent. The home run rates were nearly identical at 3.2 percent.

So, this leads to the verdict. Is it legit, and should we expect Perdomo to put together another season like this one?

Geraldo Perdomo’s 2025 Season Verdict

Given that Perdomo reached 720, the sixth most in baseball, it does not seem like a fluke that he put up the kind of numbers he did. Not that Perdomo was a compiler, in the three previous seasons, his career high in plate appearances was 500.

The jump in exit velocities and bat speed is notable, though both are still low. It is essential to remember that Perdomo is still 25 years old and could continue to improve as he enters his prime years. His elite glove means he will stay on the field every day moving forward. He is a key piece of this Arizona club.

My biggest question moving forward is how many bases Perdomo will steal. He is not the fastest runner, but his 82 percent success rate should allow him to continue to get opportunities. While the 27 stolen bases are an outlier for his career, if you pro-rate the 2023 and 2024 numbers to his 720 plate appearances, you would get 23 and 17, respectively. So, even if they do tick down next year, he should clear the 20 stolen base bar.

I think the home run production is sustainable as well, especially given that Perdomo puts a ton of balls in play and does a good job of getting to ideal angles. The three-year gain in bat speed and exit velocity could always become four years next season, which would also help his case.

So, I see no reason why Perdomo is not a 20/20 type hitter next season with a slash that was consistent with the .290/.389/.462 slash he posted this year. There appears to be sustainability in the profile, making Perdomo a trustworthy asset moving forward.
