What happened to the Oakland A's?

They have the best statistical pitching staff in the AL. First in ERA and HR allowed. The problem is they can't hit. Willingham,Jackson,Suzuki,and Matsui haven't provided the power that the A's had hoped. They were supposed to be alot like the '10 Giants and win a lot of 3-2 1-0 ball games behind the power of their arms. In order to turn things around, they are going to have to give up one of those pitchers like Anderson or Cahill to get a legitimate bat.
