Cleveland ? Bruce Chen and Kila Ka’aihue stayed aggressive, and the Kansas City Royals kept ahead of Cleveland in their race to escape last place.

Ka’aihue hit a go-ahead double in the seventh inning to help Chen and the Royals beat Cleveland, 6-2, Sunday.

Manager Ned Yost got his 500th career victory in the majors. The Royals are 43-52 since Yost replaced Trey Hillman on May 14.

“Chen was on the attack, getting after it,” Yost said. “He stayed ahead of hitters, changed speeds and threw them off-balance. He’s capable of doing that whenever he goes out there.”

The 33-year-old left-hander, with his 10th major-league team since 1998, allowed two runs and six hits over six innings.

“I was mixing different arm angles and getting ahead in the count,” said Chen (9-7). “It all felt good.”

The Royals avoided a three-game sweep and pulled two games ahead of last-place Cleveland in the AL Central. Kansas City is 5-17 on the road since July 8.
