BALTIMORE -- To make room for Wednesday's starting pitcher Dylan Axelrod, the White Sox placed right-hander Gavin Floyd on the disabled list for the second time in two months on Tuesday.
The DL move is retroactive to August 27. Floyd has a right elbow flexor strain.
Axelrod, 27, was recalled from AAA Charlotte, where he was 7-5 with a 2.88 ERA in 16 starts.
The Sox also assigned center fielder and leadoff man Alejandro De Aza (sore ribs) to Charlotte for an injury rehabilitation assignment.
The 29-year-old Floyd is 9-9 with a 4.55 ERA over 15 starts. He left his last start Sunday against the Mariners after two innings. Floyd went on the disabled list from July 17-23 (retroactive to July 8) with the same issue. It was his first DL stint as a major leaguer.
Four of Axelrod's last five starts with the Knights have been good. He allowed no more than one run in four of the five.
