The Minnesota Twins announced that left-hander Danny Coulombe has been placed on the 15-day injured list due to a left forearm extensor strain, following the earlier placement of Byron Buxton on the seven-day concussion IL. To fill the roster spots, they selected the contract of outfielder Carson McCusker and called up right-hander Zebby Matthews, who will start today against the Brewers. Coulombe, who has been exceptional this season, has not pitched since Wednesday, and his injury could keep him out for only a few weeks, though further updates are expected later today.
