Jr. Joins 600 Club

We broke the news here on 1320 "the score" that Ken Griffey Jr. broke a milestone that only five players had broken before him.  Griffey Jr. hit home run number 600 today against the Marlins' Mark Hendrickson. 

Thanks to the wonderful world wide web we have the footage of the glorious event so check it out.

Our question to you, where does Griffey Jr. rank among all players of all time?  It's obvious he's in the category of best centerfielder ever, but could he rank about players like Barry Bonds or even Babe Ruth?
