He hit a two-run home run to left field in the third inning of the Phillies' 5-2 victory. It was Howard's 30th homer of the season, setting a franchise record with five consecutive 30-homer, 100-RBI seasons. He had been tied with Chuck Klein, who had four consecutive 30-homer, 100-RBI seasons in 1929-32.
Howard was unaware of the mark until after the game.
"That's a great feat," Howard said. "It hasn't really hit me right now, but I'm sure that when I kind of look back on things and reflect on the season I think that's something that will hit me and I'll definitely be proud of."
It also was Howard's 252nd career homer, which put him in sole possession of third place in Phillies history. Howard had been tied with Pat Burrell.
Howard needs seven more home runs to tie Del Ennis for second place.
Mike Schmidt holds the franchise record with 548 homers.
