CLEVELAND — Corey Kluber kept the Cleveland Indians in the game long enough to get to Kansas City’s bullpen.Kluber pitched into the eighth inning and pinch hitter Michael Bourn had a big two-run double, leading the Indians to a 3-0 win over the Royals on Friday night.Cleveland got its first hit of the game against Bruce Chen in the fifth inning, but Kluber and two relievers made sure a three-run seventh was enough. Carlos Santana had an RBI single before Bourn came up his clutch swing.Kluber (7-5) allowed three hits and struck out eight in 7 2-3 innings. The right-hander, a bright spot in a rotation that’s struggled most of the season, worked out of a bases-loaded, one-out jam in the fifth.“He certainly stays composed,” Indians manager Terry Francona said.
