The Nationals optioned Weems to Triple-A Rochester on Sunday, Bobby Blanco of MASNSports.com reports.

EDGE Analysis

Since Weems was unlikely to be available for the next two days after covering 2.1 innings out of the bullpen while giving up three earned runs on four hits in Saturday's 11-5 loss to the Phillies, the Nationals opted to move him off the 26-man active roster. Washington recalled Mason Thompson from Triple-A to fill Weems' spot on the active roster and in the bullpen.
