The Kansas City Royals defeated the Philadelphia Phillies 9-8 on Sunday as Billy Butler recorded a franchise-record 7 RBIs.
Butler hit the first grand slam of his Major League career in the fifth inning.
Butler had been 2-for-15 with one RBI in the Royals' first five games entering Sunday.
"It was just a matter of time with Billy Butler," Royals manager Ned Yost said. "You knew he'd break out and do some damage."
