Injuries are unpredictable, they can happen to anyone. We've put ourselves in a damn good position to overcome injuries with our lead.
Anyways, if a starter gets injured, here are our backups:
1. Julian Tavarez (when Jon Lester returns)
2. Kason Gabbard
3. Devern Hansack
4. David Pauley
5. Daniel Haigwood
Tavarez has been solid in the 5th spot, Gabbard was good in his only start this year, and uhh hopefully we don't have to use Hansack. Pauley sucked last year. Haigwood is on the 40 man roster, was acquired from Texas this year.
For relievers, we have:
Craig Breslow
Manny Delcarmen
Craig Hansen
Edgar Martinez
Kyle Jackson
Emergency position players:
C-George Kottaras-Solid prospect, has great plate discipline. But as we learned in 01 and 06, we cannot lose Tek. He is crucial to this team.
1B-Eric Hinske-Already with the team. No prospects are close to the big club.
2B-Alex Cora-Would start if Pedroia got hurt. Jeff Natale, Jed Lowrie are waiting in the wings.
3B-Kevin Youkilis-Would play 3rd if Lowell got hurt, and Hinske would move to 1st. Chad Spann is waiting in the wings.
OF-WMP, Hinske-The obvious 2 backup options. Brandon Moss and David Murphy are the first two minor league options, as I doubt they want Ellsbury up so soon.
