Gary Gaetti was a late season addition to the 1998 Cubs. He helped them win the wildcard. Who will ever forget the Homerun he hit in the one game playoff against the Giants that sent the Cubs into the NLDS?
This year Gaetti joined the Astros as a hitting instructor after Jimy Williams was fired. I don't know how good of a job he has done. But he sure has made Carlos Beltran a great hitter!
