Mark Reynolds was arguably a one-tool player, as he had power, but not much else.

Playing 12 seasons with stays in Arizona, Baltimore, Cleveland, New York (AL), Milwaukee, St. Louis, Colorado, and Washington, Reynolds smacked 298 Home Runs and had 1,283 Hits, but batted only .236 and struck out a whopping 1,927 times, including leading his respective league four years in a row (2008-11).  Reynolds was also a poor fielder and had a lifetime bWAR under 10.  

Putting it bluntly, he will be fortunate to get on the ballot.

Mark Reynolds was certainly adept at hitting Home Runs and as a Diamondback he hit 121 of them including a 44 Home Run campaign in 2009.  His power puts him on this list but his game was not multi-faceted and it came with a lot of deficiencies.    Reynolds struckout in more than one third of his plate appearances and he exceeded 200 three times with Arizona, all of which were National League leading.  His 223 whiffs in 2009 remain a single season record.  Reynolds also made a lot of errors, as he was a league leader in that twice as a D-Back.  Despite that his power game is strong enough to keep him on this list for a while.
