This is a tough call, considering two of the top five rotations in the league will likely come out of the AL West (no, sorry, not the Mariners and Athletics).
In Texas, they let C.J. Wilson fall to the Angels, but replaced him with Japanese phenom Yu Darvish. They are also working on transitioning last year's closer, Neftali Feliz, to a starter for 2012.
Returning from the group last year will be Alexi Ogando, Matt Harrison, Derek Holland and Colby Lewis.
Ogando had an encouraging rookie season in 2011 that was marred only by the hefty workload that wore him out as the season came to a close. If he doesn't earn a spot in the starting rotation this year, he could work from the bullpen as a middle reliever.
Harrison, Holland and Lewis all took starts for the team in the playoffs, so they're all obviously qualified for a starting position. Any combination of five from those six will be a pretty commanding rotation that won't give opposing teams anything to look forward to.
However, the Angels have a similarly intimidating, reinforced set of starters as competition. The aforementioned C.J. Wilson will be joining Jered Weaver, Dan Haren and Ervin Santana to instantiate dominance.
The fifth spot is up for grabs and is the only potential weakness in this rotation.
The first series between these two teams will be a magnificent clash of titans. Disregarding hitting for now, I think the Rangers have the advantage.
Answer: Texas Rangers
