St. Louis Cardinals starting pitcher Adam Wainwright is still looking to find his old form in 2012, and he'll be on the mound vs. the Kansas City Royals on Sunday with a chance for his second quality start in a row. On May 22, Wainwright threw a complete game shutout vs. the San Diego Padres, but his season has still been up-and-down since then. He followed that up with a quality start, but then gave up seven earned runs to the New York Mets in the next start. He then gave up three earned runs in 5.2 innings vs. the Houston Astros before allowing only two earned runs in seven innings to the Chicago White Sox in his most recent start. He'll be opposed on Sunday by Royals starter Luis Mendoza a part-time starter who has been thrust into the rotation as of late, giving up three earned runs in 11 innings in his two starts since being moved into the rotation. Mendoza has never faced the Cardinals, either in relief or as a starter. Game date/time: Sunday, June 17, 1:15 p.m. CT Location: Busch Stadium, St. Louis, Mo.
