The Blue Jays will use their 12th starting pitcher — most in the major leagues this season — when Chien-Ming Wang takes the mound in Chicago against the White Sox on Tuesday. Manager John Gibbons confirmed reports that the club will sign the Taiwanese right-hander, who has been pitching in the New York Yankees’ farm system. Details of the pending deal were not disclosed. “He’s got experience,” Gibbons said. “They say he’s throwing the ball pretty good. He’s been up here and he’s been successful. I don’t think his stuff’s what it used to be, but we still think he’s pretty good.” Wang, 33, finished second in Cy Young Award voting with the Yankees in 2006 but has been a middling starter the last five seasons, also seeing action with the Washington Nationals. He has pitched in 48 big-league games since 2008, posting a 5.44 ERA. Wang had been pitching with the Yankees’ Triple-A affiliate, but reportedly used an opt-out clause of his contract on Friday in order to join the Jays. Tuesday’s starting spot would have been that of 25-year-old right-hander Chad Jenkins, who has been solid but unspectacular in three starts this season. “This gives Jenkins a little more time to develop,” Gibbons said, adding Jenkins needs to make his breaking ball more consistent and keeping him in the minors will ensure he gets steady work.
