Manager Ned Yost selected Chris Young over Kris Medlen to start for the Kansas City Royals against the Toronto Blue Jays on Tuesday in Game 4 of the American League Championship Series.
Young has made only two starts since July 28, giving up one run in 11 1/3 innings.
The 6-foot-10 right-hander appeared as a reliever in Game 1 of the Royals' division series with the Houston Astros, giving up a run in four innings. He was 11-6 in 34 appearances, including 18 starts, in the regular season.
Young lost to the Blue Jays, 7-5, in July. Edwin Encarnacion hit a two-run home run and Young gave up five hits and three runs over six innings. But in his 11-year career, Young has held current members of the Blue Jays to a .229 average (22 for 96) with two home runs.
Medlen was 6-2 with a 4.01 earned-run average in 15 appearances, including eight starts. He returned July 20 from elbow ligament-replacement surgery and hasn't pitched since Oct. 1.
Kyle Hendricks to start for Cubs in Game 3
Kyle Hendricks is scheduled to start for the Chicago Cubs against the New York Mets on Tuesday night at Wrigley Field in Game 3 of the National League Championship Series.
Cubs Manager Joe Maddon also said that Jason Hammel will "more than likely" pitch Game 4, depending on whether he's used out of the bullpen before that.
Hendricks was 8-7 with a 3.95 ERA this season. He gave up three home runs in 4 2/3 innings of Chicago's 6-3 victory over the St. Louis Cardinals in Game 2 of a division series. The right-hander struck out seven batters, walked none and knocked in a run with a safety squeeze.
Hendricks beat the Mets, 1-0, at Citi Field on June 30 and has won his two career starts against them, giving up one run in 13 innings.
Hammel started Game 4 at home against the Cardinals and was pulled after three-plus innings. The right-hander was 10-7 with a 3.74 ERA this season.
Matt Harvey to start for Mets if there's a Game 5
Right-hander Matt Harvey appears to be set to start for the Mets at Chicago on Thursday if the series reaches a Game 5.
