"I needed an arm," Yost said. "I was short on pitching. I've got two guys who are unavailable right now, which shortens my 'pen. So I can't use him for at least two or three days. I've got a fresh arm up here. Boom."
Coleman, a third generation Major League pitcher, last got a shot with Kansas City in May, when he appeared in two games and didn't give up a run in 2 2/3 innings.
Omaha manager Brian Poldberg told Coleman of his promotion after a doubleheader in Iowa on Tuesday.
"We weren't even able to follow the Royals' game, so nobody knew what was going on," Coleman said. "We got done really late, and [Poldberg] just called me on the phone and told me to come back inside."
Coleman is familiar with both the Twins and Target Field, as he visited with the Cubs in 2012 -- allowing three earned runs in 1 2/3 innings in a game on June 9.
On Wednesday, Coleman was looking forward to a chance to rectify that poor outing.
"Whenever you get that opportunity, you just hope to go out there and pitch well every outing you get, and hope you get another one," he said.
