Griffey passes Mantle with 537th home run

CINCINNATI -- Ken Griffey Jr. passed Mickey Mantle with his 537th career homer Wednesday, taking over sole possession of 12th place on the career list.

The Cincinnati Reds star led off the fifth inning with his first homer of the season. His drive off Jerome Williams was the third of the day off the Chicago Cubs' staff -- Bronson Arroyo and Rich Aurilia already had homered.

The homer also gave Griffey 1,538 career RBI, breaking his tie with Joe DiMaggio for 31st on the career list.

Last year, Griffey was still recovering from reconstructive hamstring surgery at the start of the season and didn't get his first homer until his 22nd game of the season, the longest such drought of his career.
