For this game, Puig had moved over from his right-field spot to get a start in center because, as Mattingly has said more than once, he's still in the mix to play there.
So Puig had to chase down Anthony Rizzo's long fly ball that was hit so hard, pitcher David Huff just assumed the ball was out and was asking plate umpire Jim Reynolds for a new baseball when the old one was snagged by Puig, as he leaped into the padded fence and tumbled to the warning track.
For his part, Puig finished dressing and joked that he was headed toward the hospital, before saying an ice pack at home will do.
"Ouch, that hurt," Puig posted on Instagram, with a photo of the play.
Puig is scheduled to start Thursday night against San Diego.
