That's the 25 right now. By opening day, one of those pitchers will lose their spot and the 25th man will be added to the bench. Pagan currently has the upperhand with Cedeno needing a huge Spring. The most likely pitcher to lose his spot is currently Wade Miller (who is topping out at 84 mph after 25 pitches). But if he builds up some strength and they decide to go with a long relief role for him, Ohman or Wuertz might start the year on an optional assignment if everyone else is healthy -- of course Miller, Ohman and Dempster are all trade candidates this spring too.
