I'll happily admit I never saw this coming for Willis. His ratings were good but not great when he joined the league and have never exceeded 60 since, but he has just gone and done his job season-in and season-out, and is still doing so at age-41.
Truly remarkable that he now becomes just the third player in MLB history after Walter Johnson and Dick Redding to reach 350 wins. That 3.38 lifetime ERA ain't too shabby, either.
