Adenhart has a little more upside.
However, the Twins rotation is Santana, Liriano and mediocrity.
Garza has a good chance of starting next year.
The Angels have the other Santana, Lackey, the good Weaver and Escobar tied up for 3 years minimum plus Colon and Saunders (who would be their only lefty and is doing really well in a hitter's league in AAA).
Adenhart is 3 years away.
