The move was revealed on the transactions page at MLB.com.
The 24-year-old Turner was the ninth overall selection in the 2009 draft by the Detroit Tigers out of Westminster Christian High School in St. Louis. He made his major league debut in 2011 with the Tigers, barely a month after his 20th birthday, and has since been traded to the Miami Marlins (July, 2012) and the Cubs (August, 2014).
Turner pitched in eight games (six starts) with the Cubs in 2014, going 2-4 with a 6.49 ERA. The 6-foot-5 righthander nearly missed all of this past season with both elbow and shoulder issues, pitching in just two games for the Cubs’ Double-A affiliate at Tennessee.
Turner was, at minimum, a top 26 overall prospect in each of his first three years in the Tigers’ organization, according to both Baseball America and Baseball Prospectus. His major league results have been uneven, though, as he has an 11-25 career record in 61 appearances (51 starts), with a 4.97 ERA. He has 192 strikeouts in his career to 107 walks.
It is the White Sox’s second waiver claim from the Cubs in less than two months after also acquiring third baseman Mike Olt on Sept. 5.
