He handled 29 plays in his zone, per fangraphs, and 22 OOZ plays. But when he played LF this year, he saw only 11 plays in zone and handled 8 of them, with only 3 OOZ plays made.
So either his range increased dramatically in the smaller RF, or he lined up closer to the fringes of his zone a lot in RF, which he might have done at any time when there was a second baseman standing in shallow RF.
I'm saying he might be a Shift Benefactor...
