» May 17, 2002: After the Twins score three times in the top of the 14th, the Yankees come back to win, 13–12, on Jason Giambi's one-out grand slam, hitting the first pitch from reliever Mike Trombley over the RF fence. It is the 21st time in history that a player has hit a game–winning grand slam -- the ultimate grand slam -- with his team down by three runs. Babe Ruth, in 1925, was the only previous Yankee to have performed the feat. Giambi's home run is one of six by New York as each team has 20 hits. The last time that two teams reached 20 hits was also on May 17—1996. Baltimore beat Seattle, 13–12 on 41 hits total.
