The Yankees suck........their pitching sucks, they lineup is old and I can't stand their ownership group.
Their big problem this year has been due to injury...too many guys ending up on the DL way to often. As for their pitching, Mike Mussina (15 wins so far), Andy Pettitte (12 wins so far), and Mariano Rivera (27 saves so far) are still pretty decent.
Rest of the lineup, it's hard to understand how this lineup is not winning more games IMO. Jeter has had an unusually off year, only batting .286, when he is normally over .300, and they never send him to 2nd anymore which I've still yet to figure out...he still has his speed cause you can see that on the field. When Jeter struggles the team struggles...but even the best player have off years.
If Jeter can get his swing back like he almost always does late in the season, if they get Posada
back in here in a few days who always does well late, and if Matsui can get back in there this wk....they should make a decent run at closing their 7 game gap.
My D-backs will always have 2001 over the overrated Yankees.....

Yes they will. But the Yanks will always have 10million championships over everyone else...including the Dbacks.
