August 28th, 1971
On this day in 1971, pitcher Rick Wise hits two home runs, including a grand slam, en route to a complete-game victory in the Phillies' 7-3 defeat of the Giants. Five weeks earlier, the 25 year-old right-hander also hit two round-trippers and threw a no-hitter against the Reds on the same day. And they say pitchers need a designated hitter.
