More durable rotation? With Buchholz and Matsuzaka in the rotation? Just for shits and giggles, here are the composite numbers from 2009...
Yankee rotation: 70-41 162GS 1008IP 931H 422ER 360BB 911K 3.77ERA 1.28WHIP 8.1K/9IP 2.5K/BB
Boston rotation: 54-32 119GS 743.1IP 733H 324ER 232BB 685K 3.92ERA 1.30WHIP 8.3K/9IP 2.9K/BB
Similar WHIP, yankees better in ERA, sox a smidge better in K/9IP and better in K/BB. But the Yankee rotation made 162 starts last yr and threw 250+ more innings. With NY's lineup and now with a pen either boasting Hughes or Joba in that setup role, this rotation is better suited for their team and is deeper. When your only question mark is your #5 hole, things are going well. Plus, with Vazquez added, we have 4 pitchers who routinely throw mid 90s and 3 guys capable of ringing up 200 guys in a season (maybe 4 by the time Joba rules are out). Now, I understand there will be a regression for Vazquez since he's coming to the AL East, but a full season out of DiceK or Buchholz will move some of those numbers northward for Boston too. But if those guys put in a full season, the sox will be happy. That's the biggest question. Can DiceK and Buchholz give them 32 starts in a season. That is something that is yet to be determined.
