"The doctors said that it was the right thing to do," Gardenhire said. "They said he'd be out three to four days, and we can't afford that right now. Going into a National League park you're going to be thin anyway [without the designated hitter]."
Ramirez, however, expressed the belief that he did not have a concussion. He said the problem was that the doctor asked him to repeat the months of the year backward, and the Dominican Republic native was unable to do so.
"I feel the same," Ramirez said. "The doctor asked me some questions, and I answered. So I don't know. I'm very disappointed right now."
Ramirez said he would talk to Glen Perkins, the Twins' union player representative, to see if he could appeal the decision. Perkins said he would look into the matter and was unsure if Ramirez could appeal.
"If he asks me, I'll have to look into it," Perkins said. "I don't really know. I just know concussions are an issue in all sports. So I'll have to dig into it a little bit. I would imagine he'll have to spend the seven days."
Herrmann, meanwhile, hit .238/.311/.285 with no homers, five doubles and 12 RBIs in 43 games with Rochester. He started 29 games behind the plate with seven starts in left field and five starts at designated hitter.
He saw his first Major League action last year, when he played in seven games as a September callup, going 1-for-18 with an RBI and a walk.
