The Pirates placed Mears on the 60-day injured list Tuesday while he continues to recover from arthroscopic surgery for his right elbow, Rob Biertempfel of The Athletic reports.
Biertempfel relays that Mears had the procedure Feb. 9 for the purpose of cleaning up scar tissue in his right elbow. Since his surgery wasn't a reconstructive one, Mears should have a chance at being available to rejoin the Pirates in June once the 60-day window ends. The Pirates signed veteran reliever Heath Hembree to take Mears' spot on the 40-man roster and in Pittsburgh's bullpen.
