The right-hander, who was not in big-league camp this spring, spent the entire 2013 season at Triple-A Charlotte, compiling a 6-14 record with a 4.25 ERA. The 27-year-old has pitched in 33 major league games over two seasons with the Toronto Blue Jays, White Sox and Boston Red Sox.
In a 2011 start with the White Sox, the Texas native nearly pitched a perfect game, retiring the first 21 batters before the Minnesota Twins’ Danny Valencia led off the eighth inning with a double. He finished with a complete-game one hitter.
Over two seasons with the White Sox, he was 3-7 with a 6.14 ERA in 28 appearances (nine starts).
