7. Adrian Beltre
2009 defensive stats: 110 starts, .959 FPCT, 14 errors.
Beltre, a tremendous, spectacular defensive player, takes over for the popular Mike Lowell, who lost most of his range last season as he recovered from hip surgery.
Beltre, 31, hit 25 or more home runs from 2006-08 with the Mariners, but fell to eight last year as he was hampered by injuries. The Sox believe his power will be enhanced by playing half of his games at Fenway rather than cavernous Safeco.
