The Mets placed Polanco on the 10-day injured list with left ankle bursitis.
Polanco has dealt with a left ankle/Achilles issue throughout the season and it's become clear the nagging injury has greatly affected him, leading to a lowly .148/.201/.230 batting line with two home runs over 37 contests. The Mets didn't reveal a timetable for Polanco's return, but it wouldn't be surprising if he was shut down for the season.
