Graham was placed on the 15-day DL on Wednesday, Rhett Bollinger of MLB.com reports.

EDGE Analysis

Graham's shoulder swelled up after he threw two-thirds of an inning in Tuesday night's win over Tampa Bay. With the team looking to take no chances, Graham will hit the DL, which frees up a roster spot for Blaine Boyer, who was activated from the disabled list Wednesday afternoon. Graham, who will be eligible to return August 10, holds a 5.15 ERA on the year.
