KANSAS CITY, Mo. — Bruce Chen had the Boston Red Sox popping up and out.
Chen outdueled Jon Lester and the Kansas City Royals defeated the Boston Red Sox 5-1 Thursday night.
The Royals won for the 16th time in 20 games since the All-Star break. The Red Sox, who have the best record in the American League, lost for only the third time in 10 games.
Chen retired 15 on fly-ball outs.
"A phenomenal job," Royals manager Ned Yost said. "He was ahead in the count most of the night. He commanded the ball down, commanded the ball up, changed speeds. Anytime you see a lot of popups, out-front swings, you know Bruce is on his game and he got an awful lot of them tonight."
Chen, who was making his fifth start since beginning the season in the bullpen, did not allow a runner past first base until the eighth and retired 11 in a row in one stretch. He gave up five singles, walked one and struck out two before leaving with two outs in the eighth inning.
"Movement on the ball," Chen said of the high number of fly outs. "They see it and at the last moment, it cuts or sinks or they're a little bit out in front. I think, also, the combination of different pitches, not repeating the same pitch or same pattern has to help. Brett (Hayes, the catcher) did a really good job of reading the hitters."
Hayes, who was just called up from Triple-A Omaha, had not caught Chen since spring training.
