Adam Dunn is hitting .165. He's 55-for-334 (including a remarkable 3-for-78 against lefties) and is about to reach 400 plate appearances. How rare is this? Since 1920, only 33 players have had 400 plate appearances and hit under .200 -- "led" by Dal Maxvill's .175 mark for the 1969 Cardinals. Carlos Pena and Mark Reynolds both achieved this dubious accomplishment last season.
