Yankees' Alex Rodriguez ties Willie Mays with 660th career homer

— -- Alex Rodriguez has matched Willie Mays for fourth on the career homer list by hitting No. 660, possibly setting up a legal showdown with the New York Yankees over a $6 million payment.

Rodriguez, who entered Friday night's game in the eighth as a pinch hitter, connected off Junichi Tazawa of the Boston Red Sox to reach the milestone with his sixth home run in a successful return from a yearlong drug suspension.

Homer 660 was hit nearly five years after he became the youngest player to reach 600 -- on Aug. 4, 2010.

Because of injuries and serving the longest performance-enhancing drug ban in major league history, A-Rod went 1,731 days between historic homers, 306 more than Mays, The Say Hey Kid. Home run king Barry Bonds didn't even need two years (612 days) to reach his Godfather's mark after hitting his 600th, according to STATS.
