1. Jacoby Ellsbury
2009 defensive stats: 150 starts (center), .994 FPCT, 2 errors.
Ellsbury played only center field last season, but he started 36 games in 2008 in left field and 15 in '07. Francona said Ellsbury was initially disappointed about his switch, but he'll be entering the season never having committed an error in left.
As the leadoff hitter, he improved his on-base percentage from .336 in '08 to .355 last year. The Red Sox would like to see another such leap this year.
