Pressly was placed on the 10-day injured list with right knee inflammation Friday, Chandler Rome of the Houston Chronicle reports.
Pressly blew the save and took the loss Wednesday in Arizona when he allowed two runs (one earned) on a hit and two walks in one-third of an inning. It's possible that the injury contributed to his struggles, and the right-hander will have at least a week and a half to recover. In spite of Wednesday's rough outing, Pressly should reclaim closing duties upon his return. Hector Neris and Ryne Stanek are candidates for ninth-inning duties while Pressly is sidelined.
