The Pirates have placed outfielder Gregory Polanco on the 10-Day IL with left shoulder inflammation, the team announced. Outfielder Jason Martin has been recalled in his place. It’s the same shoulder on which Polanco underwent major surgery in the offseason, resulting in a month-long absence at the season’s outset. The move is retroactive to Wednesday, however, so it may just be a minor setback for the 29-year-old.

The lefty has struggled in his first 42 games for the team this season, slashing just .242/.301/.425 (89 wRC+) with an easily-career-high 29.3% strikeout rate. Polanco’s (left) throwing arm has graded out as subpar for the first time in his six-year big-league career thus far, so it’s certainly possible the shoulder is still giving him issue.
