Gavin Sheets' Grip On Padres' First Base Job Is Loosening

[Randy Holt]

There was a brief moment over the weekend where it looked like San Diego Padres first baseman Gavin Sheets was shaking off the early season rust and morphing back into the excelling, change-of-scenery bat that he’d been for much of 2025. After a solo home run early in the game, Sheets sent a three-run homer into the seats in the bottom of the ninth for the second walk-off victory in as many days. 

Unfortunately, either side of that has been plagued with a rather downtrodden performance from Sheets. Worse yet is that it’s extended to both sides of the ball. 

We’re still operating within a small sample here in the middle of April, but Sheets has been below average by wRC+ standards (92). Through the roughly 50 plate appearances he’s logged as of the middle of the Mariners series, he’s at a .220/.250/.440 line. His strikeout rate, at 26.9 percent, is abnormally high even against the lower standards set forth when he was at the height of his struggles with the Chicago White Sox. He’s not compensating with deep counts either, as a 3.8 percent walk rate is less than half of what he turned in last season. 

One concerning trend is that Sheets has apparently lost all semblance of plate discipline. He’s chasing pitches at a 41.1 percent clip (a 10 percent leap from where he was last year) and swinging inside the zone at a slightly lower rate. His 49.7 percent swing rate would represent the highest of his career. There isn’t any discrimination in pitch type, either. He’s swinging at more fastballs than anything but is chasing just about anything regardless of pitch type. 

What’s even worse for Sheets is that there’s no compensating with the glove. He has been transitioning to full-time work at first base after spending the bulk of his time on the outfield grass last season. However, he’s also turned in -3 Outs Above Average thus far, which ranks 34 out of 35 qualifiers at the position. Only Bryce Harper’s -5 figure is worse. He has a 62 percent success rate against a 69 percent estimated success rate. He’s particularly struggling moving to his right, which is an area in which he’d been only slightly below average (-1) in his career prior to this year’s sample. Plays simply are not being made for a player who was awarded the heaviest run at the position on a roster loaded with first base archetypes. 

And that’s an important consideration within all of this. Sheets is struggling massively not only to put the ball in play but to help a delicate pitching staff record outs. This is the same roster that features a defending Gold Glove winner in Ty France in addition to Miguel Andujar and Nick Castellanos. Each of France and Andujar have looked strong at the plate while Castellanos’ results are not indicative of the more solid under-the-hood figures with which he’s working. 

Which means that despite what Sheets has working in his favor – namely the fact that the Padres are currently winning games after a slow start – the runway is going to begin to get shorter. Sometimes in the early season, you see a player (like Castellanos) who is executing solid process and running into bad luck. Others you see a player who gets outside of his general performance and needs to reign it back in before the outcomes begin to fall in line. 

Given the Padres’ roster construction, Sheets needs to be the latter. Otherwise, the depth chart has the ability to change rather quickly. Especially as Sung Mun Song gets closer to returning and thins out some of the available innings on the bench.
