Easily the best season for Royals third baseman Mike Moustakas now has easily his best game.
Moustakas singled in two runs in the sixth inning to whet his appetite, blasted a grand slam in the seventh and put the cherry on top with a three-run dinger in the ninth to set a franchise record with nine RBI in a game.
The huge performance lifts his slugging percentage to .460, its highest point since June 29.
