INDIANAPOLIS — The Twins designated right-hander Boof Bonser for release or assignment on Tuesday to make room for Carl Pavano on the 40-man roster.
Bonser missed the entire 2009 season following shoulder surgery in Spring Training to repair a torn rotator cuff and a torn labrum. The 28-year-old is eligible for arbitration for the first time this winter.
In 2008, Bonser began the year in the Twins rotation but by the end of May had been demoted to the bullpen due to his ineffectiveness. Bonser went 3-7 with a 5.93 ERA that season and posted an overall 18-25 record and 5.12 ERA in 163 career games with the Twins.
The Twins acquired Bonser from the Giants organization in November of 2003 in the same trade that brought
pitchers Joe Nathan and Francisco Liriano to Minnesota in exchange for catcher A.J.
