The St. Louis Cardinals announced prior to Sunday's game that they have activated right-handed pitcher Adam Wainwright (right elbow inflammation) from the 10-day disabled list and optioned right-handed pitcher John Brebbia  to Memphis (AAA).  
Wainwright is slated to start Sunday's game in San Diego, his first appearance since winning a 5-3 decision on April 17 over the Chicago Cubs. He missed 19 games while on the disabled list, and made an injury rehabilitation assignment for the Springfield Cardinals (AA) on May 7, posting 5.0 scoreless innings against Tulsa.
Wainwright, 36, is 1-2 with a 3.45 ERA in his three starts this season.
Brebbia was charged with the loss in the Cardinals 2-1 defeat in 13 innings last night at PETCO Park, despite striking out four in his 2.0 innings of relief. He's 0-1 with a 2.70 ERA in six relief appearances, striking out 14 in 10.0 innings pitched.
Wainwright is the second pitcher the Cardinals have returned from the disabled list this weekend, joining reliever Brett Cecil who was activated on Friday. Prior to the weekend series, the Cardinals placed pitchers Carlos Martínez (right lat strain) and Tyler Lyons (mid back stain) on the 10-day disabled list.
