The 28-year-old Ross joined the White Sox on a minor league deal in March, which came after he saw MLB action with the Rangers (2012-14) and Red Sox (2015-17) over the previous six seasons. Ross had some success during that span, particularly during the 2012, ’13 and ’15 campaigns, and combined for a 3.92 ERA with 7.46 K/9, 3.27 BB/9 and a 52.2 percent groundball rate in 330 2/3 innings. He didn’t show a significant platoon split, either, as he held same-handed hitters to a .250/.331/.381 line and righty-swingers to a .269/.344/.376 mark.
Injuries, including elbow and back problems, limited Ross to nine major league frames a year ago. In his return to the mound this season, he struggled in Charlotte, where he logged an 11.81 ERA with 9.28 K/9 and 14.34 BB/9 in 10 2/3 innings.
