how about what their numbers on the season are. Both Bard and Belliard had a hot month just like any player in baseball would over the course of a 162 game season. doesn't mean they are good or even average though. both are terrible players at this stage of their careers who will not be on the 2010 Washington Nationals roster.
Bard's numbers are better than Nieves over the course of the season, and career.
