Santana dealt with some swelling near the end of his next start last Thursday at Marlins Park, resulting in the Braves' decision to skip him in the rotation on Tuesday night. Santana is 3-0 with a 2.41 ERA and four quality starts in five turns this season.
Making his first start since undergoing Tommy John surgery on May 7, 2013, Floyd gave up only one run on six hits in seven innings in Tuesday night's 2-1 win over the Cardinals.
