Per Rotoworld:
Obviously I don't know Jeter like you all (or the style of baseball the Yankees will play with their new look lineup,) but outside of the obvious decline in speed he would get from getting older, many of his baserunning and speed indicating statistics did tail downward (2B/3B, OOB, BT, SB, etc.) Jeter hits and can still get on-base at a decent clip so it isn't a total head scratcher, but more of my intent with this post was in regards to him possibly declining further this season.New York Newsday reports that Derek Jeter will bat leadoff for the Yankees this season, with Johnny Damon hitting second.
Jeter has hit atop the order plenty during his career, but has been primarily a No. 2 hitter, including hitting there in 134 of his 149 starts last season. Manager Joe Girardi explained the switch by saying that he's been impressed with how Damon has looked in the No. 2 hole this spring. Newsday speculates that the changes signal that Brett Gardner will beat out Melky Cabrera for the center field job, because by moving Jeter to leadoff the Yankees would avoid having back-to-back lefties in Gardner and Damon.
