Tom Glavine is inching closer to 300 wins -- and retirement. Needing 10 victories to reach the milestone, the Mets' ace sounds as though he plans to call it quits after this season. "I don't want to sit here and say definitively," Glavine said Friday, when Mets pitchers and catchers took their physicals. "If I don't win 300 games for some reason, I will play -- unless my arm blows out and that's the end of it."
