All ADP values from ESPN. Analysis based on 5x5 roto, mixed, non-keeper 10 or 12-team leagues.
Jesus Montero (ADP 187)
Depending on the rules in your league, Jesus should become catcher eligible soon enough. Just don't forget about him if he is listed at DH, he is going 10th among catchers but should be at least the 8th best catcher. I would take him over Yadier Molina or Alex Avila. He should be safe for .280 with 20 HR, with RBI dependent on the much-maligned Mariners lineup, which I believe will improve this year.
Ryan Doumit (ADP 260)
Deep league or 2 catcher league, you can take a chance on Doumit, who is now DH'ing which could help him stay in the lineup, and more opportunity if Mauer or Morneau goes down. One of the few with a chance to produce like a top 12 catcher if everything works out.
Devin Mesoraco (ADP 260)
Another deep league special, this rookie has the skills to eventually be a good hitter, but he's probably just too young right now, and it's not yet clear if he will get at bats. Remember his name for later.
Overrated at catcher:
J.P. Arencibia (ADP 218)
