The House That Dewey Built looks at Papelbon’s first/second half splits. The results are clear but far from dramatic, and are consistent with the way a lot of closers are. I’d be more concerned if it were not for his 25 career innings in the postseason, in which Papelbon has a 0.00 ERA, 7 saves and has struck out 22 batters while allowing just 16 baserunners. If he was just burning out at year end, he wouldn’t be doing that. The lesson instead is that, as the Yankees have done with Rivera most years, Papelbon’s workload should be held down in the regular season even at the cost of the occasional game to ensure he remains fresh enough to keep dominating in October.
