Gallagher was placed on the 10-day injured list Sunday with a right shoulder impingement. The move is retroactive to June 17. Gallagher hasn't seen game action since Wednesday, so the transaction will be backdated by a few days. The 28-year-old is without a timetable for his return but will be eligible to be activated next Sunday. Sebastian Rivero was recalled from Triple-A Omaha in a corresponding move and will serve as the backup to Salvador Perez.
Gallagher has gone 6-for-15 (.400) in his last six games. The 28-year-old only sees a small share of playing time as backup to Salvador Perez. Gallagher has shown some improvement in recent games, but just two of his 10 hits this season have gone for extra bases (both doubles). He's slashing only .227/.271/273 with no home runs, one RBI and three runs scored across 49 plate appearances.
