Outside of David Ortiz, there isn't likely to be a lot of money made by pure DHs in 2012. Open spots are limited and teams seemed to have learned their lesson on signing aging DH-only types to lucrative deals.
1. David Ortiz (36) – Ortiz had a fantastic 2011 campaign in which he posted a line of .309/.398/.554 with 29 home runs. He also lowered his strikeout rate and posted the best BB/K ratio of his career (0.94). His age is a bit of a deterrent and he shouldn’t be in a position where he has to play the field everyday. Both factors will limit his market and possible contract length, but teams will certainly be interested in his bat.
2. Jason Kubel (29) - Kubel gets marked down a bit since he's not much of a defender, at all. He should be limited to signing with an American League team where he can DH, maybe playing a few games in the outfield here or there. Kubel's a solid enough hitter, capable of a line around .275/.335/.450 with 20-25 homers when healthy.
