Henry Schulman covered the event for the San Francisco Chronicle. There's lots here, including the tribute from Aaron, a call from the commissioner, the person who retrieved the ball (wearing a Mets jersey, no less) and this bit of trivia:

Bonds also got a visit from Bacsik, who congratulated the new home run king and got an autographed bat in return.

Bacsik's father, also named Mike Bacsik, pitched for Texas and Minnesota from 1975-80. On Aug. 23, 1976, in a Rangers-Brewers game, the elder Bacsik faced Aaron two months after The Hammer hit his final career home run. Aaron singled off him in two at-bats. Thus, the Bacsiks became the only father and son each to face different hitters with 755 home runs.

"If my dad was gracious enough to give up a home run," Bacsik said, "we both would have given up 756."
