I noted at the start of the season that while Clemens has more wins than Maddux, his lead has been shrinking since 1991.
Maddux had a pretty good year last year. Clemens, a little less so, but it wasn't too bad. Both of them had ERAs significantly better than the league average. Clemens, though, seems less likely to come back. I can't imagine that anyone will pay him that much money again.
After this year, Maddux is within striking distance. Clemens' lead was 15 at the end of last season; now it's 7.
Maddux keeps rolling along and I believe he has another year left on this contract. Of course he could get hurt. But barring injury, he looks good for another 10-13 wins next year. I don't know about Clemens.
I still think it's cool that the #8 and #9 career wins leaders are simultaneously active. I can't imagine it will ever happen again. I don't know that Clemens will get to Kid Nichols and Pud Galvin, but I wouldn't put it past Maddux if he stays healthy. Probably not next year, when he ought to finish with about 358 wins. But maybe after the following, if he sticks around. If he stays healthy for two more years, it's possible he could pass Warren Spahn and end up #5 on the all time list.
