31. Chris Iannetta (Rockies career WAR: 7.0)
The blocky catcher affectionately named SpongeBob by teammate Ryan Spilborghs, is the last catcher on this list. Also, the only homegrown catcher as well, which shows the ineptitude the Rockies organization has been at developing and signing at this position.
He was drafted in the 4th-round of the 2004 draft. But at least fans have this brick-wall of a man to look back on fondly. His best year came in 2008 where he slashed .264/.390/.505 with 18 HR/65 RBI producing a 125 OPS+ and 3.2 WAR.
