I'm not saying he has been a success or that he should keep his job (his track record says no but every action ownership has taken says yes), but there has seemed to have been a pivot in recent years toward more athletic, more defensively-minded players.
Since drafting Sabato, their first-round position-player picks have been:
Noah Miller - defensive wiz, zero power
Brooks Lee - great hit tool, not exactly Vince Coleman but profiled as having the hands and arm to be good defensively at 3B
Walker Jenkins - true 5-tool player, any FO would've taken him with that pick in that draft regardless of philosophy
Kaelen Culpepper and Marek Houston - shortstops with power being their weakest tool
In free agency, their biggest position player signings in each of the last 3 years (non-Correa division) were signed with defense in mind: Vasquez, Santana, Bader
If this has been a philosophy change, he's implementing it with the speed and urgency of someone turning an ocean freighter. And none of these pieces have really impacted the core yet. But there has been a definite increase in balls put in play (up to 65% of PAs from 56%) and decrease in strikeouts (nearly 2 fewer per game) since The Year Of The Strikeout in 2023.
(There's also been a nearly 50 point drop in OPS and they're scoring 0.62 fewer runs per game since then, but that's for a different discussion on another day)
