If I were a futures bettor, I would grab some Oakland. They are automatically discounted in comparison to Seattle and LA because they have players in their lineups and rotations who are lesser known.
The Angels lineup is very good. However, there are some questions in their rotation with the injuries - never been a big fan of John Garland, who always has a high batting average against and has a ton of balls put into play on him. Ervin Santana was highly touted, and has started OK, but was terrible last season. Joe Saunders is serviceable, but not sure if he is as good as he is pitching right now. Weaver has been very solid. So, without Lackey and Escobar, they don't really have much more than Seattle or Oakland in the rotation.
Seattle bullpen has been awful so far and even with the return of Putz, you still have to get him the ball with a lead in the 9th. Their bats haven't been very good so far either, but I think some of their hitters like Vidro and Johijma will come around. Overall not a great lineup, but I don't think its that terrible. Rotation wise, Batista and Silva give up tons of hits, and Washburn only slightly better. Bedard and Felix are the guys, which again, puts them pretty much even with everyone else's rotation in the division, outside of Texas.
I think Oakland will be hurt by the loss of Duch. I think he has potential to be a very good starter once he builds up the endurance.
