The incident took place Thursday when Diamond's first offering to Hamilton in the fourth inning sailed over the Texas slugger's head. Home plate umpire Wally Bell kicked Diamond out of the game immediately and he also tossed Ron Gardenhire after the Minnesota manager came out of the dugout to argue.
Diamond said he would appeal the suspension. He was also fined an undisclosed amount.
Diamond has a 10-5 record with a 3.04 earned run average in 20 starts this year.
