Tonight, Barry Bonds hit a home run to pass Willie Mays for third on the all-time list and Roger Clemens won his second game of the season to pass Tom Seaver on the all-time win list (at 18th with 312). When I was a kid Mays and Seaver were considered the best player and pitcher of their era. I think it's highly symbolic that the two men who are the best of their generation and arguably better than Mays and Seaver passed those two legends in such important categories on the same night.
Now, what it symbolizes I have know idea. But keep in mind that tonight Dusty Rhodes tied his career high in saves (4). That's highly significant.
