Jeremy Peña is off to a superb begin. He’s additionally been one of many least productive hitters in baseball. How’s that for a lede?

If I advised you that with none extra context, maybe you’d suppose Peña was struggling on the plate however making up for it within the discipline. Yet, the previous Gold Glove winner presently has -2 OAA and -5 DRS on the season. So a lot for that idea. Much on the contrary, Peña is on fireplace on the plate. Over the primary six weeks of the 2024 marketing campaign, he's batting .313 with a 129 wRC+. And whereas his .351 BABIP is probably going unsustainable, his .327 xBA ranks second amongst certified American League batters. His .363 xwOBA ranks within the eightieth percentile, an enormous step up from his .305 xwOBA (twenty second percentile) in 2023. Most spectacular, he has reduce his strikeout fee down to simply 14.0%, ninth lowest within the AL. His strikeout fee has improved from the thirtieth percentile in his 2022 rookie marketing campaign to the 61st percentile final season, and now it sits within the 92nd percentile in yr three.

However, for those who look up from these percentiles on Peña’s Baseball Savant web page, you may be stunned by crucial quantity of all of them: His batting run worth is zero. The line on the worth spectrum is the faintest shade of blue, sitting a few quarter of an inch nearer to “poor” than “great.” That doesn’t appear proper. Indeed, out of 485 batters to see a pitch this yr, Peña is the one one with a wOBA and xwOBA above .350 and a damaging batting run worth, in line with Savant. It’s not onerous to know why he’s an outlier. Typically, when a participant is hitting wherever near in addition to Peña, he offers at the very least some optimistic worth to his membership.

Metrics like wOBA and xwOBA are context impartial, whereas Baseball Savant calculates run worth by contemplating the runners on base, the variety of outs, and the ball and strike rely for every discrete occasion. If you are taking that normal methodology a step additional and in addition think about the inning and the rating, you get a statistic like Win Probability Added (WPA) – though Peña would possibly ask that we please, please cease taking the methodology a step additional. According to WPA, Peña has value the Astros excess of he has given again in 2024. Houston ranks second to final within the AL with -3.82 offensive WPA this season. Peña (-1.03) is liable for greater than 1 / 4 of that damaging WPA. Only two gamers have contributed to the crew’s misfortunes greater than Peña: the now-optioned José Abreu and a deeply slumping Alex Bregman.

Don’t let the truth that Peña has solely the third-worst WPA on his personal crew overshadow simply how a lot damaging worth he has contributed this yr. His -1.03 WPA is the eleventh lowest within the majors and sixth lowest within the AL. In different phrases, his actions on the plate have decreased his crew’s probabilities of successful by greater than all however 10 different gamers within the sport. Yet, for those who take a more in-depth take a look at the underside of the WPA leaderboard, you’ll shortly see that one factor is nothing just like the others:

Lowest WPA in 2024

No minimal PA

Yes, Peña is the one participant on that record with a wRC+ that’s higher than league common. You’d must broaden the desk to 53 gamers earlier than anybody else would seem with a wRC+ above 100. (For what it’s value, that participant is Colton Cowser.) It’s not that good hitters can’t have a low WPA – proper now, 30 certified batters with a wRC+ over 100 have a damaging WPA – however it’s uncommon to see a participant hitting this nicely with a WPA this poor. When a participant is getting as many hits as Peña, you’d suppose a few of them must are available higher-leverage spots. Similarly, Peña is making outs at a low fee this yr (his OBP is 15% higher than league common). In idea, that ought to restrict the variety of occasions he can come up brief with the sport on the road.

From 1974 (way back to our WPA leaderboards go) to 2024, there have been 42,194 particular person batter seasons (min. 1 plate look). In solely 2,667 of these (6.3%) has a batter had a wRC+ above 100 and a WPA under zero. Only 204 occasions (0.48%) has a batter posted a wRC+ above 100 and a WPA under -1.00. And solely as soon as (0.002%) has a batter recorded a wRC+ above 128 and a WPA under -1.00 — Jeremy Peña in 2024.

I don’t count on Peña to take care of this distinction all yr. He has nearly 80% of the season left to play, and I’d count on each his wRC+ and WPA to regress towards the imply. Still, what he has already achieved is surprisingly historic. Through the tip of April, Peña was sporting a 138 wRC+ and a -1.27 WPA. Dating again to 1974, there have been practically 300 calendar months of Major League Baseball (i.e. April 1974, May 1974, June 1974… April 2024). In that point, there have been tens (if not a whole lot) of 1000's of particular person participant months. Yet, by no means has a participant had the next wRC+ and a decrease WPA in a single calendar month than Peña in April 2024. Few have even come shut. It might sound onerous to imagine, however having clicked by each month of every of the previous 50 years on a customized leaderboard, I can guarantee you it’s true.

The final hitter to even put up a wRC+ above 100 and a WPA under -1.00 in a month was… Peña in April 2023. Huh! Meanwhile, the final hitter with a wRC+ above 130 to rank among the many backside 10 in WPA was Daniel Vogelbach, who had a 132 wRC+ and a -0.89 WPA in August 2022. The final participant with a wRC+ above 120 and a WPA under -1.00 was Kevin Pillar in April 2017, who had a had a 124 wRC+ and -1.1 WPA over 110 plate appearances. Going additional again, different gamers this century who got here near Peña’s numbers embrace Dustin Pedroia in August 2009 (136 wRC+, -1.02 WPA) and Javy Lopez in June 2004 (132 wRC+, -1.16 WPA).

So, how did Jeremy Peña accomplish such a singular feat? Although he didn’t floor right into a triple play with the bases loaded and the Astros down by one within the backside of the ninth, he's liable for the worst offensive sport by WPA thus far this season. (Note: For the subsequent few paragraphs, I’m going to be utilizing Baseball Reference WPA. It’s not precisely the identical as ours, however it’s fairly related and permits me to make use of the Stathead device to check particular person participant video games over a number of seasons.)

On April 17, Peña went 0-for-5. In 4 of his 5 at-bats, he got here up with runners on base and made the ultimate out of the inning. To cap it off, he grounded right into a double play to finish the ballgame within the backside of the tenth, stranding the tying run on third. That’s one heck of a nasty sport. According to Baseball Reference, no different batter has had -0.6 WPA in a single sport this season, and solely two extra have even gotten to -0.5 WPA. Here are all 12 gamers who've had a sport with -0.4 WPA or worse in 2024:

Teams begin each sport with a 50% win expectancy. By the tip of the day, the winners may have elevated their win expectancy from 0.5 to 1.0, whereas the losers have decreased theirs from 0.5 to 0.0. Therefore, if a person batter finishes a sport with a WPA under -0.5, meaning the remainder of his teammates within the lineup mixed for a optimistic WPA. That’s greater than just a little embarrassing; maybe we want one other golden sombrero-type time period to explain such a efficiency.

If -0.5 WPA is dangerous, -0.6 WPA is much worse. It’s not straightforward to compile a lot damaging worth in a single sport. Only 5 different lively gamers have ever had a WPA worse than -0.6 in a single contest:

Instead of getting sidetracked by the truth that Sean Murphy owns the highest two spots on that record, we have to hold speaking about Peña. Because, whereas his efficiency on April 17 goes a great distance towards explaining his low WPA, it doesn’t inform the total story. If you take away that one sport from the info set, his wRC+ would solely get larger. Yet, his -0.66 WPA in April nonetheless would have ranked under some other AL batter with a wRC+ above 100.

According to his sport logs, Peña has solely had a optimistic WPA in 11 of 35 video games this season. What’s extra, he hasn’t had many massive moments to counteract his worst showings. Although he has been a top-25 hitter within the AL by wRC+, he doesn’t even have one of many high 200 video games within the AL by WPA (utilizing Baseball Reference WPA once more). His two most efficient video games presently rank 225th and 233rd, and each of these outings got here in May. His most efficient outing in April ranked 443rd that month. He could also be racking up hits, however his timing couldn’t be worse.

Peña shortly developed a popularity as a clutch performer throughout his rookie season. He hit .364 with a 198 wRC+ in high-leverage spots, and his 1.20 clutch rating ranked ninth amongst certified AL hitters. He was Houston’s finest hitter within the playoffs, posting a 187 wRC+ en path to incomes ALCS and World Series MVP honors. That stated, his efficiency ever since is an efficient reminder that clutch (or un-clutch) hitting isn’t a sustainable ability. That was dangerous information for the Astros final yr within the ALCS, when their 2022 postseason hero went ice chilly, hitting .160/.192/.160 with the bottom WPA within the lineup. However, it would simply be excellent news this time round. The Astros aren’t going to show issues round except their bats cease developing brief in massive moments, and Peña has nowhere to go however up.
