Bregman doesn’t take too many fastballs down the middle. Correa takes an inordinate amount of those. Is there a breakdown of pitches they watched on first pitches? Bregman is quite selective and spits on anything but what he is looking for first pitch because as his short swing allows him to protect while still hunting that fastball when behind in the count. Correa since his return gets behind watching the pitch he should hit, chases a breaking ball. Fights a few off inside cause he can’t clear his hands on the inside pitch. Then either watches the 3rd strike down the middle with multiple runners on base or hit a weak ground out to short to end the inning.
Since he’s been back his pitch recognition and timing is just off. If it’s inner third he is not starting early enough to clear his hands. If you watch the contact Bregman makes from that side angle the bat is making contact with the ball way in front of plate as he recognizes it and clears his hips and hands to get to the ball. Correa just hasn’t been able to do that yet and you wonder if it’s hesitation about hurting his back.
i hope this is the series where he arrives.
