Barry Bonds became the fourth player in Major League Baseball history to hit his 600th home run last night. He hit it off of Kip Wells of the Pirates. Bonds is fourth on the all-time home-run list behind Willie Mays (660 home runs), Babe Ruth (714), and Hank Aaron (755). Impressively, it took Bonds just 710 at bats to go from 500 home runs to 600. He could very well pass Hammerin' Hank.
