Bonds hit a 3-1 pitch from righthander Matt Kinney into "McCovey Cove" beyond the right field fence at SBC Park in the fifth inning, a three-run shot that gave the Giants a 5-4 lead.
Mays was in attendance and came on the field with a torch in hand after Bonds reached home plate. Bonds put his arm around his godfather and posed for pictures to commemorate the milestone.
