I think he is saving the wear and tear on his arm by staying away from the split. He's doing pretty well getting by on just a fastball. Last year he did much the same thing. There was that one game when he blew a save and he threw nothing but fastballs and people started asking where's the splitter? Varitek defended him and said that he's a fastball pitcher so I call for the fastball. At the end of the year and the playoffs, he worked in the splitter and an ocassional slider. I think he'll do the same as he starts to lose a little on the fastball as the season wears on.
I don't get theis Bard for closer talk yet. I'm not excited to get rid of Papelbon. I am excited that if Bard continue this progression that he and Papelbon will shorten games to 6 or 7 innings. That is a formula for success. Bard just recently learned to throw consistent strikes. By this point in his development, Papelbon was already a big time closer. Some guys develop slower than others and he may become a dominant closer or late inning guy. He isn't there yet. Papelbon has been ther for some time. Comparing the two guys, I would say that it is clear that Bard has a good curve. Papelbon has never developed consistent offspeed stuff, but neither has Mo. Bard throws harder, but IMO Papelbon's ball has more movement. That's the key. That's why Papelbon is elite.
