Here are the worst LF'ers in 2023, according to OAA:
-19 Schwarber
-12 Profar
-11 Beni
-9 Yoshi
-9 Soto
-8 de la Cruz
It shows Yoshida at 0 on balls hit "in" and -2 going "back," so that jives with the short wall preventing missed plays in those directions. He's -4 to the left and -4 to the right. My guess is, if he played in Yankee Stadium, he might be -6 back, -4 in, -4 to his right and -6 to his left.
