CLEVELAND (AP) — Corey Kluber was handed a big lead early in the game and the rest was simple.

Kluber became the American League’s first six-game winner and the Cleveland Indians beat the Kansas City Royals 11-2 on Sunday.

The Indians led 9-0 going into the fifth, leading to a stress-free afternoon for the reigning Cy Young Award winner, who gave up two unearned runs in seven innings, scattering eight hits.

“If you have a nine run cushion, obviously you have a bigger margin for error,” Kluber said. “They’ve always been pretty aggressive against me. It can work both ways. You can get some early contact and get some quick outs.”

Kluber (6-2) was backed by four hits from Yan Gomes, including a three-run homer. Jose Ramirez also hit a three-run shot and Michael Brantley had a two-run homer as the Indians had 15 hits.
