The Twins designated catcher Steve Holm for assignment in order to add lefty Phil Dumatrait to the 40-man roster according to a team press release. Dumatrait was recalled along with Anthony Swarzak, while Jose Mijares hit the DL and Jim Hoey was optioned to Triple-A Rochester.
Holm, 31, had just two hits in 18 plate appearances with the Twins this season. He was recalled after Joe Mauer hit the disabled list, and produced a .231/.400/.269 batting line with Minnesota's Triple-A affiliate this year. MLBTR's Mark Polishuk took a look at Minnesota's bullpen woes last week.
