The White Sox declined to tender contracts to infielder Dan Johnson and right-hander Anthony Carter on Friday while also parting ways with right-hander Philip Humber, who was claimed on waivers by the Houston Astros.
The Sox 40-man roster now stands at 37, allowing room for potential additions via trades or free agency.
Humber pitched a perfect game in Seattle on April 21 but struggled in the following months. He pitched like an All-Star Game candidate in the first half of 2011, his first season with the Sox, before finishing with a 9-9 record and 3.75 ERA. He was 5-5 with a 6.44 ERA while dealing with an elbow flexor problem in 2012 and did not win a game over his last 15 starts at home.
Carter went 4-6 with a 4.60 ERA and two saves over 39 appearances for AAA Charlotte last season. He had 32 saves over seven seasons in the Sox organization.
Johnson played in 14 games with the Sox last season, hitting .364 and three homers — all in the final game of the season against the Indians in Cleveland. He hit 28 homers for Charlotte in 2012.
Humber is a native of Nagodoches, Texas, and a former first-round draft pick out of Rice University.
