He's 36. He's brittle, pitching in just five games last season. And he has made 30 or more starts only three times in his past nine seasons. But when healthy, he can dominate, especially in a pitchers' park such as Shea Stadium.
If Pedro is Pedro, the Mets will cruise into the National League playoffs as the favorites behind the 1-2 punch of newly acquired ace Johan Santana and Martinez. But if Pedro can't sustain his health, the Mets come back to the rest of the pack.
Here's betting Pedro bounces back with 15 wins after combining for just 12 the past two years.
