I'm nitpicking on phrasing here, but in an era of defined bullpen roles, few teams have more than 1-2 arms they use in the 8th inning. The real problem is that the Twins 8th inning arms are really 7th inning arms. Any options from within are going to be 6th-7th inning arms as well either because they're rookies or because of their "talent ceiling" so, yes, trade. Bullpen pieces are often cheap, like an high A-baller or PTBNL, but they're also a crapshoot. Fuentes was perfect for the Twins in '10, but BP arms also tend to be streaky. I think they should upgrade, but I do wonder if Fien/Boyer could get hot again and it evens out. Odds of Boyer having 2 hot streaks, however, seems unlikely given his career.
