The White Sox have placed starter Philip Humber on the 15-day disabled list, retroactive to June 17, with a right elbow flexor strain, the team announced Friday. The Sox also purchased the contract of Brian Bruney from Triple-A to take Humber's spot on the 25-man roster.
Additionally, outfielder Kosuke Fukudome was designated for assignment.
Humber had struggled since throwing his perfect game April 21, posting a 7.47 ERA in 10 starts since. A year after having a 3.75 ERA, Humber's ERA has ballooned to 6.01 this season in 67 13 innings.
Fukudome was on a rehabilitation assignment with Triple-A Charlotte, where he had three hits in 11 at-bats. In 51 trips to the plate over 24 games this season, Fukudome hit .171 with a .294 on-base percentage and no home runs.
The White Sox have 10 days to place Fukudome on waivers, release him or trade him. With the move, Jordan Danks may have won a job in the majors with the White Sox -- the 26-year-old has five hits in 13 at-bats with a stolen base since being brought to the majors after Fukudome hit the disabled list.
Bruney appeared in 23 games for Charlotte this season with a 1.85 ERA, making three starts and 20 relief appearances. The 30-year-old righty spent time with the White Sox in 2011, throwing 19 23 innings with a 6.86 ERA.
Either Bruney or Dylan Axelrod will likely replace Humber in the Sox rotation while he's on the disabled list.
Four of the team's top-10 prospects and a former All-Star are among the 19 nonroster invitees to White Sox big league camp this spring.
The team announced Monday that prospects Michael Kopech, Zack Collins, Zack Burdi and Spencer Adams have all been invited to camp next month. Everth Cabrera, an All-Star in 2013 for the San Diego Padres, Cody Asche, Cory Luebke and Geovany Soto are among the eight minor league free agents who also received an invitation. Pitchers and catchers report to camp in Glendale, Ariz. on Feb. 14 while the team holds its first full-squad workout on Feb. 18.
Kopech was acquired in the Chris Sale trade in December while Collins and Burdi were both selected in the 2016 amateur draft. Adams was drafted in 2014.
Signed earlier this month, Soto is expected to earn a spot on the 25-man roster. Soto, who played for the White Sox in 2015, finished last season with four home runs and an .809 OPS in 86 plate appearances for the Los Angeles Angels.
Cabrera, who produced 4.6 Wins Above Replacement between 2012-13, hasn't played in the majors since he appeared in 29 games for the Baltimore Orioles in 2015. Luebke, who has twice had reconstructive elbow surgery, finished with a 9.35 ERA in nine games for the Pittsburgh Pirates last season. Asche blasted 31 homers with a .240/.298/.385 slash line in 1,287 plate appearances since 2013 with the Philadelphia Phillies.
Other minor league free agents include: left-handed pitcher David Holmberg, right-handers Blake Smith and Anthony Swarzak, and catcher Roberto Pena.
White Sox minor leaguer pitchers Aaron Bummer, Brian Clark, Jace Fry and Matt Purke, infielders Nicky Delmonico and Danny Hayes, and outfielder Courtney Hawkins also have been invited to camp.
