Kind of worried he is regressing offensively. His OPS and slugging is down 100 points from last year and his ISO is about where it was in '22.
Yeah, I noticed that too, so I did some poking around. He's trailed off a bit lately, and is currently sporting a 101 OPS+. Still very valuable with the defense and the speed though. He leads the team position players with 2.3 fWAR. (Abreu is 2nd at 1.6 fWAR.)
He's played in all 42 games though, which helps WAR but probably indicates he might need a break. He leads the Sox in total fielding innings with 370.
Rafaela has also had 42 games to this point with 356 fielding innings. Abreu is #3 at 36 games, 263 innings.
As for the bat, his SLG v. RHP is pretty close to what it was last year. Also, his overall split (.100 OPS) between LHP and RHP is consistent with last year. So he hasn't platoon-pumpkined, although he is facing more lefties. Overall though his numbers
are down v. both RHP and LHP. Interestingly, he's been really productive in high leverage situations this year (per bRef) which mitigates things somewhat, I'd expect.
Last year he had a very rough May (.670 OPS) and August (.602). I don't know if he played somewhat injured in Aug. or came out immediately, but looking at the logs he just had an 0-9 stretch followed by an 0-10 stretch. Those (per savant) seemed to be an unlucky mix if anything - there were no shifts in patterns that I could see. This year seems more even so far (SSS) in that he's not logging long stretches of not getting on base.
Compared to last year his K% and BB% are slightly better (but by a few percentage points, so basically the same.) His hard-hit % is down a tad, but again, in the range of basically the same, given SSS. So it comes down mostly to field outs.
Last year he had 133 field outs in 332 ABs (40%). 32% were hard hit, and the average LA was 11 degrees. This year he already has 77 field outs in 172 ABs (44%). 29% were hard hit, and the average LA was 2 degrees. That's not a huge difference really - a 4% swing. But that's basically the difference between last year and this.
I didn't think I'd see anything, but I sorted the data anyway and something did jump out. His ratio of pulled-pitches to hits is pretty far down. He's only batting .140 overall when he pulls. 3 triples, 3 singles, 1 error, 35 field/force outs.
Both Duran's 2023 and this year feature a fairly even spread of putting balls in play - slightly favoring an up-the-middle approach. He's not pulling
more - it's just the pull results are bad.
And there, the results are pretty stark. Out of 43 balls in play to the right (pulled) only two balls were hit at an angle of 30 or more. 7 were between 10 and 25, which contain two of the triples and a single. 33 were an angle of 9 or lower. And 25 of those were 0 or lower. So he's grounding when he pulls.
Of the 35 field outs to right balls in play, 18 of those were on fastballs of some type (5 hard hit.) He's still getting good results on fastballs hit to center and left this year. He just seems to be grounding out when he pulls. That's the same for pulled offspeed (0-5).
Some of that is probably luck. . .but it could also be approach. Last year he put 80 balls in play to the right. 4 were hit at an angle of 30 or more. 19 were between 10 and 29. 57 were an angle of 9 or lower. And 40 were 0 or lower. Still a groundball hitter, but you can see the mild trend in downward angles in 2024. Couple that with a 41 hard hit % decreasing to 33% - and there you have it I think. There's something about the swing when he pulls.
