Could be, but Bonds isn't done. He has the highest on-base % in MLB this year (.479), and obviously he can still hit the long ball. As I mentioned earlier in the thread Bonds knows full well A-Rod will be breathing down his neck in a few years and therefore wants to put this record out of sight. I wouldn't be surprised if he ends up around 850. ...or higher. Especially if he can get a gig in the AL as a DH.
Make that .495 -- an incredible number at any age. If he rests his body DHing in the AL he could keep going for a while.
