The Miami Marlins placed infielder Derek Dietrich on the 15-day disabled list with a right knee contusion, retroactive to August 19.
This makes room on the roster for Oswaldo Arcia, who the Marlins claimed off waivers from the Tampa Bay Rays. Dietrich hit .303 prior to the the All-Star break in 273 plate appearances, but has struggled in the second half, hitting just .195 in 87 plate appearances.
Overall for the season, Dietrich is slashing .276/.369/.403 with four home runs and a .339 wOBA. We currently project him to continue to struggle over the remaining course of the season, posting just a .689 OPS.
