Matt Guerrier began this week with a nice-looking 2.67 ERA in 26 appearances for the Twins, but a 12/8 K/BB ratio in 27 innings showed that he was anything but impressive and then the 35-year-old right-hander got knocked around for four runs in an ugly outing Tuesday night.

That inflated his ERA to 3.86 ERA and now the Twins have designated him for assignment, ending the reunion with a player who was a very dependable setup man in Minnesota from 2005-2010.
