Jones left the second game of the series after just one inning due to what was announced as an illness. He was later taken from Target Field to the Hennepin County Medical Center during the middle innings for further evaluation.
"I just didn't feel myself," Jones said. "So, I guess the team wanted to make sure I was OK. But I feel fine today."
Jones went 0-for-4 at the plate and was replaced in the field by Matt Angle in the bottom of the seventh.
Orioles manager Buck Showalter said he made out two lineups on Wednesday, one with Jones in it and one with him out.
Jones was his usual upbeat self during the team's pregame stretch on Wednesday, which was a good sign of how he felt, as Jones was more subdued a night earlier.
"You can tell he's a lot more engaged," Showalter said. "I should've known something was up because usually he's real engaging. He always sticks his head in and we shoot the breeze a little bit."
After feeling fine through the Orioles' pregame stretch and batting practice on Tuesday, Jones' symptoms popped up early in the game. When it continued to persist through the top of the second, Jones left the game and was replaced by Angle.
The Orioles decided shortly thereafter that it would be best to have Jones go to the hospital and go through a number of tests to figure out what exactly was going on.
Said Jones of how long he was at the hospital: "Too long. I should've been there for two minutes, but was there a little bit longer. But I'm all right, and that's the important thing."
Jones said he did not know, nor did he care, what they were testing him for at the hospital. All that mattered was that he was healthy and back in the lineup a day later.
"It was nothing that's going to keep me out of a game," Jones said. "It took me out of one, but it won't keep me out of another."
Showalter said he still was not entirely sure what Jones was dealing with, but thought it was primarily due to dehydration.
