Each Monday morning, we highlight 10 players who stood out to us based on their underlying Statcast metrics. Data will usually be through Saturday of that week, but may include some data from Sunday games. These are not full scouting reports, but often serve as good early indicators of prospects who might be ready to break out or are demonstrating MLB-ready skills.
Last week, we discussed Nelson Rada’s path to success in the major leagues and discussed how Joe Mack’s combination of elite defense and optimized batting approach projects him as a very valuable player. For the final week of the regular season, we’ll discuss:
10 Statcast Standout
Daniel Espino, RHP, Guardians
I often get asked fantasy baseball questions, as people erroneously assume I am a fantasy baseball expert. A while back, I received a query about Espino. I replied: “I will be shocked if he ever pitches again. And if he does, I’ll be even more shocked if he’s anywhere close to the guy he was.”
I’ve never been more delighted to be wrong.
1,241 days between strikeouts.
Cleveland #Guardians 24yr old RHP prospect Daniel Espino picked up his 1st strikeout since 4/29/2022 while with Double-A Akron for Triple-A Columbus today vs St. Paul.

Back in 2022, Espino looked like one of the best pure-stuff pitchers we’d seen in a long time. He was blowing hitters away at Double-A and looking like he was months or maybe weeks away from doing the same on a major league mound. Then he stopped pitching. There were rumblings about knee soreness. Espino disappeared, with no clear explanation. Much later in the season, it was announced that he also had shoulder soreness—always ominous for a pitcher.
Early in 2023, Espino was diagnosed with a shoulder muscle tear, which would require surgery and a lengthy 12-14 month recovery window. Then in 2024, Espino re-injured his shoulder, this time requiring rotator cuff surgery. Most pitchers struggle to come back from one major shoulder injury, let alone two.
It takes a special kind of athlete to grind back from that kind of injury history. If you want to be great at any endeavor, it’s usually not enough to just be supremely talented. You also need to embrace the grind of boring work. Compared to playing in real games, there aren’t many things less interesting than rehab—especially three years of it—and it comes with all the doubts and fears that maybe you won’t ever get back to the player you were before you got hurt.
Let’s take a look at what Espino’s first inning back on the mound in three years—he gave up three earned runs on three hits with a strikeout in what is an extremely small sample size—looked like under the hood:
Espino’s fastball shape isn’t all the way back, as he was getting about average ride given his arm slot. His velocity, however, which averaged 98 mph and touched 99, was extremely encouraging. If we assume he’ll ramp up a little as he settles back in, this is looking like a potential plus-plus pitch again. Most importantly, the command of the pitch looked very on point:
That’s a lot of zoned fastballs, mostly in the top third of the zone.
Espino’s slider looks to be a plus-plus pitch, with premium velocity and huge vertical separation off the fastball. His huge two-plane curveball looks promising, as well. He flashed a changeup, but it didn’t impress from a shape standpoint.
If Espino’s velocity and command have returned, it suggests he might not be far off from the electric pitcher he was before his three-year injury hiatus. I, for one, am very excited to be able to cover him again and look forward to seeing him in action in the Arizona Fall League.
Zach Cole, OF, Astros
There is a cognitive bias in baseball prospecting that results in “old” prospects tending to get overlooked. Generally speaking, once a player demonstrates who they are as a player, they very rarely break out of that mould. This is especially true the older the player gets.
Baseball America’s scouting report on Cole had him with 55 power, 60 run, 60 field and 70 arm, but he’s ranked 22nd on the Astros’ Top 30 due to questions about his hit tool, is graded as 30. He was also recently ranked 30th in the Astros organization by FanGraphs.
A lot of this was due to an abysmal season in Double-A last year in which Cole struck out 38% of the time as a 24-year-old. He repeated Double-A to start this season and was still striking out at a 36% clip, justifying the concerns about his hit tool.
However, the Astros saw enough improvement that they promoted him to Triple-A:
The result was a spectacular 240-pitch sample, with a plus-plus damage on contact profile, a potentially average hit tool and elite patience. Cole was so good in Triple-A that he was promoted to the majors, where he has just kept on mashing:
That’s elite raw power from an exit velocity standpoint, with potentially elite game power if the flyball exit velocities hold up in a larger sample. The zone contact has held up, as have the swing decisions, though. they’ve leveled out as closer to average.
You may be tempted to be skeptical about the power—don’t be. Cole’s 76.2 mph average bat speed would rank 12th among qualified batters, sandwiched between Julio Rodriguez and James Wood. He’s also showing plus-plus or better foot speed, with an average sprint speed of 29 feet/second.
What’s the moral of the story here? Don’t necessarily write off an athlete because he’s old for a level. Sometimes a player is a simply a tweak away from fully tapping into his potential. No player embodies this more than Cole, who has transformed himself from a fringe prospect into the Astros’ 2025 MiLB Player of the Year and a legitimate candidate for 2026 rookie of the year in the American League.
Luis Perales, RHP, Red Sox
Perales’ fastball averages 99 mph with more than two inches of ride above expected. That’s an easy plus-plus pitch that will play up because of his arsenal. All of Perales’ pitches operate within a 12-to-14 inch horizontal space. That means batters have very little information on what pitch type they are seeing based on horizontal movement. He prefers his 90-92 mph cutter to the fastball, using it as his primary weapon in the early going. Both the cutter and slider (the cluster around the 0 vertical movement line) grade out as plus-plus or better pitches.
The changeup should tunnel well with the fastball, and it has unicorn traits given the lack of horizontal movement. This makes it a potential fourth weapon for Perales, though I’m concerned the velocity separation from the fastball might be too large. We’ll need to see how it plays against major league competition.
Perales’ combination of tight horizontal tunneling and a plus-plus fastball looks like the stuff of nightmares. This could be a special arm for the Red Sox.
Elmer Rodriguez-Cruz, RHP, Yankees
The Yankees are arguably the premier organization for developing supinators. Supinators, generally speaking, excel at creating east/west movement and usually struggle to create a fastball with plus shape. Rodriguez-Cruz looks to be a prime example of this. Whereas Perales had a very narrow band of horizontal movement, Rodriguez-Cruz has a very narrow band of vertical movement, but a huge spread of horizontal movement.
The sinker has a ton of movement, making it effective against righties and lefties. When he executes the sinker well, it gets a ton of seam-shifted wake depth. As he gets more consistent with the pitch, it should be a groundball weapon, no matter the matchup.
The key to success for pitchers of this archetype often rests on the shoulders of a bridge cutter, splitting the arsenal. It’s highly encouraging to see this present, and Rodriguez-Cruz uses it primarily against lefties, against whom his power sinker will be somewhat less effective.
Rodriguez-Cruz’s splitter/changeup looks like a potential plus-plus weapon, with ideal velocity separation and a ton of fade and depth. His sweeper doesn’t get elite horizontal movement, but it has a lot of seam-shifted wake lift that should add to its deception, especially in that velocity band. There’s likely room for refinement there as he figures out what shapes he can produce and which ones work for him.
There’s a lot to like with Rodriguez-Cruz’s arsenal, and he’s in the right organization to help him maximize it.
Jhancarlos Lara, RHP, Braves
Lara’s cutter/slider might be a true 80-grade pitch given the shape and performance. In Triple-A this season, he’s thrown it around 56% of the time. When batters swing at the pitch, he’s getting whiffs 51.4% of the time, good for an excellent 19.7% whiff/pitch. The fastball has great velocity but has well below-average shape, and his sinker has a similar velo/shape divergence. However, due to his great velo, both pitches should play as at least average.
Lara’s command has been spotty, but the raw stuff is enormous. He should be a weapon out of the bullpen, where he can overwhelm hitters who aren’t familiar with him.
Deyvison De Los Santos, 1B/3B/DH, Marlins
What happened to De Los Santos? The underlying data suggests something has gone wrong after coming over to the Marlins from the Diamondbacks in a trade last year.
Let’s start at the beginning. Here’s what De Los Santos looked like before the trade:
That’s a plus-plus damage-on-contact profile, with better contact in the air, decent contact rates and an aggressive approach that would likely be easily exploited at the major league level. Then he got traded to the Marlins and everything fell apart (note that the 90th EV is computed for the entire season, not the stint):
One might be tempted to point to the change from the Pacific Coast League to the International League. While that may have been part of the issue, there’s a substantial change that isn’t reflected in the charts above: Spray angle.
Specifically, the horizontal direction of batted balls:
STINT/METRIC2024 Arizona2024 Miami2025 MiamiSpray Angle-1 Degrees+10 Degrees (oppo)+8 Degrees (oppo)Fly Ball EV93.6 mph93.0 mph87.9 mphHard Hit Launch Angle11.4 degrees10.3 degrees6.4 degreesSwing %57.0%58.3%51.5%Chase Swing%45.5%49.1%36.7%
The data suggests the Marlins thought they needed to fix De Los Santos, as he’s made two significant changes. First, they had him wait on the ball just a tick, going from an approach that was mostly up the middle to one that was significantly oppo-heavy. The assumption here is that the two are correlated and that this was an intentional change. This season, they’ve had him focus on fixing his chase rates, with which he has made substantial progress:
However, being more patient and selective has taken away the key to his success—aggressive, damage-on-contact swings. We see that in the abysmal contact quality on fly balls, which is critical for hitting home runs.
I’m of two minds here. On the one hand, De Los Santos looks “broken”. On the other hand, he’s made substantial progress in improving his swing decisions. If he can maintain that while getting back to his old ways, he might be a substantially better version of the batter he was before he landed with the Marlins. For some players, leaning into their strengths is often superior to fixing their weaknesses and taking away what made them great in the first place.
Hopefully, De Los Santos can blend his new-found improved selectivity with his 2024 swing for improved results.
Kemp Alderman, OF, Marlins
We took an early look at Alderman a couple weeks ago. And while his zone contact rate has come down as expected, he still looks like a future masher:
While the Marlins potentially did a poor job with De Los Santos, they’ve done an incredible job with Alderman, who has a what could be a 70-to-75 grade damage-on-contact profile. Alderman possesses 80-grade raw power, which he combines with good launch angles. No matter which way you slice it, it’s at least plus-plus raw and game power, with a direct path to 75-or-better game power.
What could this profile look like in the majors? One possible answer is Kyle Schwarber, if everything breaks right:
Eduardo Valencia, C/DH, Tigers
Baseball is a crazy sport. Occasionally, we see a player go from looking like he has absolutely no chance at making it to looking like a solid bet to be at least an average player or better at the highest level of the sport. Valencia’s rise has been nothing short of meteoric.
Last season, Valencia repeated A ball for the third time at the age of 24 after spending most of 2023 injured. That was not to be the end of Valencia’s story. With a healthy offseason, he came into 2025 a completely different ballplayer. We often attribute player successes to their team, and in this case, that may be warranted, as the Tigers started him off in Double-A despite Valencia not having found success during his brief experience in High-A.
Valencia hit .304/.359/.500 (149 wRC+) in Double-A. After his promotion to Triple-A, he did even better—.315/.400/.613 (164 wRC+) through Saturday. That slash line is fully supported by the metrics, which suggest something like a 45 hit/60 power combination with strong swing decisions.
I’m not sure I’ve seen anything quite like this. Valencia has never graced any top prospect lists, and he looked to be on the verge of being out of baseball at the end of last season. Now, he’s on the cusp of cracking the big leagues and looks poised to stay for a while.
Luis Campusano, C, Padres
You may have forgotten about Campusano—and we wouldn’t blame you.
Last season, he hit a woeful .227/.281/.361 in the majors. You will also be forgiven if his .319/.356/.491 line in 2023 has been forgotten. This year in Triple-A, though? A spectacular .336/.441/.595 line, good for a 148 wRC+.
If you’re reading this series, you probably aren’t too keen on slash line propaganda. So, let’s take a look at Campusano via a Statcast lens:
That’s easily plus-plus raw power that will play closer to a 55 grade with those launch angles. He doesn’t chase and make a lot of contact, especially against in-zone fastballs. Campusano’s top-end exit velocities are higher than he’s ever shown, and he’s married that to the plus contact rates he was showing during his successful 2023 campaign.
Liomar Martinez, RHP, Marlins
It’s rare to see a pitcher this young with such a diverse arsenal. Martinez is the rare specimen who can get plus vertical ride on his fastball, while executing a wide supination-bias east/west arsenal. The sweeper is probably the best secondary, with strong spin rates and the ability to hit 20 inches of horizontal break. The curveball should play well with the sweeper, and it gives him a pair of high-potential breaking balls.
The changeup needs work, as it doesn’t get the results or shape you’d like to see from the pitch. The splitter is likely a cutter. He’s showing what looks like a cutter and a gyro slider, but it’s a little messy.
Given Martinez’s age, this is a profile that looks primed for a massive leap forward. Baseball is a game of small adjustments, and small improvements to all of Martinez’s pitches, along with an overhaul on the changeup, could all work together to make him a top-tier pitcher.
If you’re looking for a “pick to click” in 2026, look no further than Martinez. His combination of command, pitch mix and youth suggest a breakout is right around the corner.
