Luis Gonzalez obviously got his nickname from his last name, because he already had it when he was the Cubs, and he obviously didn't hit like a Gonzo in Chicago (22 home runs in his 1 ½ years with the team).

It's not as if Gonzo's Cubs career was a total flop, however. He was acquired mid-season in 1995 (along with catcher Scott Servais), and helped lead the team to a surprising third place finish that strike-shortened season. In 1996, he had a very solid season (15 HR, 79 RBI, .271 Ave), but because he was a corner outfielder, the Cubs felt they needed more power out of that position and allowed him to leave via free agency. Ironically, Gonzo discovered his power stroke very soon after leaving Chicago. He hit 23 HRs for the Tigers in 1998, and then really blossomed in 2001, when he 57 home runs and finished 3rd in the MVP voting. He also got the game winning hit in Game 7 of the World Series that year.

Still, Gonzo enjoyed his time in Chicago immensely. One of his most treasured possessions is a ball thrown to him before he filed for free agency in 1997, signed by Wrigley Field's bleachers bums.
