The Angels still had a great first half without Tex. I think even with the addition of Holliday and Giambi, the A's have no chance for postseason play. The Angels' pitching is far superior to Oakland's.
Don't forget, the A's lost Huston Street to the Rockies, so that lowers their pen tremendously and the loss of K-Rod is not an issue. They signed Brian Fuentes, who, in my opinion, is better than K-rod, so I think the Angels still have a major advantage.
