Five toughest relievers vs. Twins

The Twins didn't mind seeing Jose Valverde designated for assignment by Detroit. Of the 38 pitchers who have recorded 10 or more saves against the Twins, Valverde was one of the five most dominant, as gauged by ERA. The all-time leader in saves vs. the Twins, by the way, is Mariano Rivera, whose 33 regular-season saves (four blown) combined with a 1.30 ERA would rank sixth on this list.
