Even in retirement, Barry Bonds remains tied to baseball intrigue.
The latest controversy occurred when the marker commemorating Bonds' record-breaking 756th career home run disappeared from AT&T Park in San Francisco. The Giants announced that they are studying surveillance tapes from the past week in an effort to figure out what happened.
The six-foot marker was mounted on a brick wall beyond the fence in right-center field.
Bonds hit 586 of his 762 career homers in a Giants uniform, playing in San Francisco from 1993-2007. In 2001, he hit a single-season-record 73 home runs. Bonds spent 1986-92 with the Pittsburgh Pirates.
His career ended under a shroud of controversy due to his connections with the Bay Area Laboratory Co-Operative, which allegedly supplied performance-enhancing drugs to dozens of athletes.
Bonds is appealing a federal conviction on an obstruction-of-justice charge that was related to his denial of involvement with illegal drugs. He was acquitted on other charges.
