In a statement, Twins general manager Terry Ryan revealed the MRI results.
"Structurally, the MRI on Scott Baker's right elbow was very similar to the previous MRI he had in July of 2011," Ryan said. "Baker will see Dr. David Altchek in New York next week for a second opinion."
Baker, who is on the disabled list retroactive to March 27 with right elbow tendinitis, was scheduled to throw 75 pitches, but couldn't get loose during his outing and was removed after facing just three batters.
"He didn't feel right," Ryan said. "When they took him out it was just because he couldn't seem to get loose."
Manager Ron Gardenhire said he was concerned about Baker's ability to adjust, as he had troubles on the mound after a delay due to the Opening Day ceremonies in Port Charlotte, Fla.
Baker, who averaged 91 mph last year according to FanGraphs, was reportedly throwing just 80-84 mph during his outing before he was taken out with just one out in the first inning.
"Not being able to make adjustments because of your arm really bothers me," Gardenhire said. "They had a little delay, had to sit back and wait a little bit, but not being able to in the heat, the whole package, that bothers me. He just didn't feel right. That bothers me."
