Willis has the numbers against the Mets to match up. Lifetime 8-1 and 1.85 era vs. them. Differenet offenses for both teams than in the past though. I would probably go with the better pitcher in Willis.
Tom is not that good anymore but he has the better team, Willis can pitch a great game and still get beat,think he may have a yr like the Big Unit did his last in ARI. I took a shot with Fla today but it's a shot.
Don't forget, other than Cabrera and Olivo, Willis has a bunch of rookies supporting him offensively. The Mets on the other hand, look like they will have a potent offense this year.
