The suspensions can be appealed. But with 17 days remaining before Opening Day, they can probably get that process done by then. Players have only so many days to file an appeal, not weeks.
The Yankees will start likely the season with a 23-man roster for at least two games, probably three. That means Damon in center, Matsui in left, Giambi at first and TBA as the designated hitter. Their spring training plans will have to change to get those players ready. Matsui has played just one game in left so far this spring.
Youth and energy are great. But whether Girardi can control players like Duncan will be an ongoing story this season. Duncan started to develop a reputation last season with his aggressive slides and this latest incident will only serve to enhance that.
As was reported in other papers, veteran players have been taking Duncan aside to tell him that he needs to watch how he conducts himself. It appears Girardi did the same the other day. The question now is whether Duncan listens.
