I've thought it's been Lopez all along. ESPN has him listed as the closer. Rotoworld has been saying he will be the closer.
I'll let people take Biddle, Borowski, Koch, Mesa, Wickman, Graves, Mac Dougal or any other closer likely to lose his job and kill your ERA/WHIP.
I think Lopez has a better chance than most of the above. He is usually available later in the draft.
...then again I thought Brandon Villafuerte and Alan Embree were good candidates for success last year. I'll cut bait on Lopez quick if he struggles, but I think he is a decent sleeper closer.
