"He might've stayed a couple innings, but then he went to the doctors," Ullger said. "He wasn't feeling well.
Before the game, Gardenhire said that he added another medication to the ones that he's already taking.
Gardenhire joined the team on the field for early batting practice on Tuesday afternoon, and he admitted before Wednesday's series finale that it probably was not the best decision.
"I screwed up yesterday by going out for that early batting practice and trying to run around a little bit," he said. "I hadn't been out in a while and that really set me back, because I was coughing all through the game and it was not fun."
The illness, which Gardenhire referred to last week as a viral infection in his esophagus, has forced the Twins to play most of the homestand with Gardenhire watching from his office. He even had to leave the ballpark early one night to go home and get some rest.
Gardenhire said that it gets worse as the day goes on.
"I wake up in the morning and feel better; I've got some nice cough medicine that knocks me out," Gardenhire said. "But as the day goes, I just have a really hard time breathing. But yeah, they're trying some more aggressive stuff, if that can be possible with that bag of drugs over there."
