KANSAS CITY, Mo. (AP) -- Alex Cobb curbed the Royals on six singles in seven scoreless innings and Ben Zobrist had three hits and drove in two runs to help the Tampa Bay Rays beat Kansas City 5-0 on Sunday.
Cobb (3-0) struck out two and walked none to pick up the victory and lowered his earned run average to 2.57. He has allowed one earned run in 13 innings in two starts since being recalled July 18.
Relievers Cesar Ramos, Joel Peralta and Jake McGee held the Royals to one hit the final two innings to finish off the Rays' eighth shutout of the season.
Cobb, a rookie right-hander who was a 2006 fourth-round pick, is unbeaten in his first seven major league starts, the first Rays pitcher to accomplish that.
