If Pettitte re-signs, I'm leaving Joba in the minors where the Yankees can monitor his pitch counts and his innings more carefully.
If Pettitte re-signs, we'll be able to hold Joba back as the first reserve so that he can pitch deeper into the season. If it were my call, he'd pitch 120-130 innings as a starter, and the last 25 innings or so out of the bullpen.
While the official schedule obviously hasn't been released yet, some enterprising fans have pieced the schedule together from other teams' official releases.
As you can see, the tradition of starting the season slowly ends in 2008. The Yanks will play 19 straight games from 4/2-4/20 (they'll play 20 straight later).
If Pettitte re-signs we'll have the depth to make it through another grueling season with a minimal number of Igawa sightings.
If Pettitte resigns will match up 1-4 against any staff in baseball.
Hopefully the Yankees will apply the full court press as soon as the ink is dry on the Arod and Mariano deals, because I think the Yankee farm is a bad matches for the pitching rich (and hitting poor) Twins or the rebuilding A's.
