Underdogs who could open the season in the Twins bullpen:

LH Aaron Thompson, 28: Twins were his fourth organization when he signed for 2012. Moved to bullpen in 2013 and lefty hitters don't like him.

RH Blaine Boyer, 33: Six organizations, plus Japan League. Retired in 2012, came back in 2013. Scouts would say: "Throws heavy ball.''

RH Mark Hamburger, 28: Signed from Twins' 2007 tryout camp. Three other clubs, plus St. Paul Saints. Mid-90s and split-finger that dives.
