Well, the last team to beat the Twins was....the Brewers, on June 15.
Minnesota has been hot as a pistol since, winning 9 straight. Granted, 6 of those wins were against two of the worst teams in the NL (Washington & San Diego) with the other three coming against the reeling Diamondbacks.
So the border rivalry moves up North to the Metrodump. Chucky vs. Nick Blackburn.
