Jeff Juden did not have a great career, but on August 25, 1995 he had quite a day. Starting against the Dodgers (who sent Hideo Nomo to the mound), he pitched a complete game and hit a Grand Slam (4th inning, off John Cummings, the only GS Cumming gave up in his career). In that same game, Gregg Jefferies hit for the cycle!
