PITTSBURGH -- The Pittsburgh Pirates placed outfielder/first baseman Ryan O'Hearn on the 10-day injured list on Sunday with a strained right quad and activated outfielder Jake Mangum from the IL.
O'Hearn was injured while playing first base in a loss to Philadelphia on Saturday. He collided with batter Bryson Stott while catching a popup in the third inning.
Signed as a free agent in the offseason, O'Hearn is hitting .291 with seven home runs in 43 games.
Mangum had been sidelined since May 6 with a strained left hamstring. He has a .260 batting average and five stolen bases in 30 games after being acquired from Tampa Bay in an offseason trade.
