Speedster, Clemens has openly said the only team he'd consider a trade to is the Yankees. He's quickly going to realize that pitching well for a team that will toil in mediocrity is nowhere near as fun as playing for the Yankees, who will be competing for the playoffs come fall. My money is on the Yankees trading for him for the stretch run, he'll go there, pitch until the end of the season, then either retire or work some way to get back to the 'Stros. Everyone knows he's playing in Houston for his family, but he's also going to realize that at 42, it's no sure thing that he'll be able to pitch at this level for years to come. He'll take his last crack at glory with the Yankees(who need him desperately), then either come home to Houston next year or retire.
Either way, the guy is amazing. To do what he's doing at his age, remarkable doesn't do it justice.
