Matsui Permanent DH

Girardi says he expects Matsui to be a full-time DH in 2009. Matsui insisted he would get surgery and work in the off season to be available for as many roles as possible and suggested he could play infield, such as first base. Huh. If Matsui is a permanent DH, will Damon be a full-time outfielder or is he too old? Does this mean the Yankees keep Abreu? If they dump Melky and Matsui is gone and Damon is at most a part-timer, they may need two new outfielders even if they KEEP Abreu.
