The Cubs cut six players from their spring roster Monday, including their 2012 minor league player of the year and pitcher of the year: middle infielder Logan Watkins and right-hander Nick Struck. Watkins was optioned to Class AAA Iowa, along with three pitchers: right-handers Trey McNutt and Alberto Cabrera, and left-hander Brooks Raley. Struck, who led the Southern League with 14 wins last year, was reassigned to minor-league camp. Right-hander Robert Whitenack, a fast-rising prospect until missing parts of the past two seasons returning from Tommy John surgery, was optioned to AA Tennessee. The cuts leave 53 players in camp with three weeks remaining before the season opener.
