Back at the beginning of August, when we rolled out the prospect report card for July, I mentioned that I was starting to get a little worried about how passive Elian Peña had become. Now, don’t get me wrong, his 105 wRC+ until that point was great for an 18-year-old in his first go-around in full-season ball in his first year in the United States, but the overall profile left a bit to be desired. Yes, he was walking at an excellent 14% rate, but he was also striking out at a 19.7% rate with lower-than-average Swing%, lower-than-average SwStr%, and higher-than-average CStr%; in other words, it seemed to me based on those stats that Peña was taking a lot of pitches, balls or strikes, and that his slightly above-average offensive contributions weren’t thanks to a preternaturally good eye for a teenager, but rather, passivity at the plate. As highlighted by the concept of SEAGER, there is a difference between good aggression, bad aggression, good passivity, and bad passivity.
One of the things I wanted to see more from Peña going forward was his ability to do damage, even if it resulted in his swing-and-miss rates going up, and related stats like batting average or on-base percentage going down. Peña has done that and then some since the calendar flipped to August. Through 12 games in the month, he is hitting .333/.423/.622 with 4 doubles, 3 home runs, and 7 walks to 18 strikeouts, with one of those doubles and all three of those home runs coming this past week.
Peña’s entire professional resume consists of what he’s done this year and 55 games in the Dominican Summer League last year, so it is pretty light all things considered. With that in mind, he has always shown a solid eye, fair pitch recognition, and demonstrated relatively positive swing decisions at the plate. I don’t want to see Peña change that and become a wild hacker swinging at everything because statistically he is bound to run into a ball here and there, but in order to develop into an effective major leaguer, he will need to hit the ball with more authority. Edgardo Alfonzo was a career .284 hitter who got on base at a career .357 rate. Mike Schmidt was a career .267 hitter who got on base at a career .380 rate. Edgardo Alfonzo is a fan favorite while Mike Schmidt is considered one of the best third basemen ever because he also slugged .527 and had a career 147 wRC+ to Alfonzo’s .425 career slugging percentage and 107 wRC+.
Now that he has been promoted to Brooklyn, it will be an interesting final couple of months for the left-hand hitting shortstop. Since Keyspan/MCU/Maimonides Park opened, it has been a favorable pitcher’s park in general, with flyballs, home runs and left-handed hitters impacted the most by the stadium. As per MLB Rule 2.01, the sight line from home plate to the pitcher’s mound to second base to center field should point due east to avoid the setting sun impacting at-bats. Facing east on Surf Avenue, well, it doesn’t really get more east. The Atlantic Ocean being about 400 feet from center/right field without much obstruction has impacted countless Cyclones home games, with winds swatting down fly balls. Peña has had his most success when pulling and elevating the ball, and his angular bat path is optimized for doing just that.
May the best force win.
Jose Chirinos
Week: 1 G (1 GS), 6.2 IP, 2 H, 0 R, 0 ER, 0 BB, 5 K (High-A)
2026 Season: 9 G (7 GS), 42.0 IP, 34 H, 16 R, 11 ER (2.36 ERA), 10 BB, 48 K, .295 BABIP (Single-A) / 12 G (12 GS), 59.1 IP, 54 H, 30 R, 27 ER (4.10 ERA), 27 BB, 61 K, .299 BABIP (High-A)
Brooklyn, which has park favors that skew heavily in the favor of pitching, often has a habit of making pitchers look better than they actually are. Beginning with Ross Peeples and his 1.34 ERA in 2001- though with Peeples, bone spurs and Tommy John surgery certainly contributed to his career as a prospect derailing- Keyspan/MCU/Maimonides Park has made its fair share of duds look like studs (no offense to any of those player, of course- I just liked the rhyme).
Jose Chirinos, surprisingly, has had the opposite effect occur. Earlier in the year, in St. Lucie, he looked great. Since his promotion to Brooklyn at the beginning of June, he hasn’t looked all that great. Much of the damage done against the right-hander came in his first bunch of starts, and he’s settled down some since then, but with the totality of everything, he has been more hittable, has been walking more batters, has been getting fewer swings-and-misses, and has been showing batted ball metric data trending in the wrong direction.
I was interested in digging into his numbers and maybe trying to figure out why Chirinos hasn’t exactly been helped by a park that has helped so many other pitchers over the last 25 years look better than they actually are/were. One thing I noticed immediately about Chirinos is that the right-hander has pretty huge platoon splits, with right-handed batters hitting .199/.276/.304 against him in 226 total plate appearances but left-handed batters hitting .274/.350/.503 in 200 total plate appearances. Baseball-Reference unfortunately does not further break down these splits by home and road, but looking at the data, he’s thrown more innings at home than he has on the road (36.2 innings in 7 home starts versus 22.2 innings in 5 away games), so basic logic would suggest that he’s had more matchups against left-handed batters at home than he has against left-handed batters on the road. The fact that Maimonides Park hasn’t helped him against left-handed batters as it has so many other New York-Penn League/South Atlantic League pitchers is a weird peculiarity. The park is usually very tough against them, and yet, of the six home runs Chirinos has allowed at home, four were against left-handed batters.
At the end of the day, based simply on stuff, I don’t see Jose Chirinos having Jacob deGrom upside despite the resemblance, or much of a particularly high upside, in general, but based on 25 seasons of Cyclones baseball, he should arguably be looking more a lot more deGromian.
