I think so, but not because I think the Yanks are great but because I think Tampa will slip up. The Rays play a lot more games on the road from this point on and they've been terrible away from the Trop.
And looking at the teams already behind the Yankees, Oakland isn't playing for this year and is fading, I don't think the Twins are that good to be blunt. The Tigers scare me a bit, but it's not like they don't have major issues as well. Texas has no pitching.
Basically I think the Wild Card comes from the East and between the Red Sox, Yankees and Rays, Tampa is the most likely to play themselves out of the race IMO.
