Reliever Sean Gallagher has been designated for assignment by the Padres, tweets Dan Hayes of the North County Times. Gallagher's roster spot is being taken by Tim Stauffer, who was activated from the disabled list.
Gallagher has a 5.40 ERA in 15 appearances with San Diego this season and a career ERA of 5.57 in 60 appearances (23 of them starts) with the Padres, Athletics and Cubs since 2007. He joined the Padres last season as the player to be named later in the Scott Hairston trade and lost a spring training bid to be part of San Diego's rotation.
The right-hander has battled a number of injuries over the last few seasons so the jury is still out on whether or not he can effectively contribute to a major league staff. MLB.com's Corey Brock (who was the first to note that Gallagher wasn't on the Padres' roster today) predicts that Gallagher will be claimed by another team before the 10-day waiver period is up.
