Didn't we already know this? He showed up on the videoboard the night of Bonds' record, saying this:
"I would like to offer my congratulations to Barry Bonds on becoming baseball's career home run leader. It is a great accomplishment which required skill, longevity, and determination. Throughout the past century, the home run has held a special place in baseball and I have been privileged to hold this record for 33 of those years. I move over now and offer my best wishes to Barry and his family on this historical achievement. My hope today, as it was on that April evening in 1974, is that the achievement of this record will inspire others to chase their own dreams."
