CHICAGO -- The Yankees placed Matthew Holliday on the 10-day disabled list Wednesday with what they describe as a viral infection, sending the designated hitter back to New York for further testing as they hope to determine the cause of his continued issues.
"We're not seeing much improvement," manager Joe Girardi said of Holliday. "I think our biggest concern is with the fatigue factor and him not eating a lot. Even if he did start to feel better, it's going to take three or four days to get his strength back. You start to add that all up, you're looking at 10 days."
In a corresponding move, the Yankees recalled infielder Miguel Andujar from Triple-A Scranton/Wilkes-Barre. New York's No. 9 prospect according to MLBPipeline.com, Andujar went 3-for-4 with four RBIs and a stolen base in his Major League debut as the designated hitter in Wednesday's 12-3 win over the White Sox.
Girardi said of Holliday that the Yankees' doctors have ruled out mononucleosis, but the actual illness remains a mystery. Holliday, 37, has not played since Saturday and started experiencing symptoms on June 17 in Oakland, believing at the time that it was an allergic reaction to a meal.

"I feel great to be here with all my teammates and with the team that signed me, the team that gave me an opportunity to come up and be here," Andujar said through an interpreter before the game. "It's special."
Andujar, 22, has played just seven games in Triple-A, where he batted .308 with a home run, a double and two RBIs. He played 67 games with Double-A Trenton to begin 2017, hitting .312 with seven homers, 23 doubles and 52 RBIs, and said he dreamed about making it to The Show this year.
"I would say it was something I definitely had in my mind," Andujar said. "You have to be positive. You have to be a positive player, a positive thinker. I definitely thought about it. I'm very happy to be here today."

There could be more roster moves in the near future. Christopher Austin is experiencing bruising in his right hamstring, according to Girardi, and the disabled list is a consideration. Austin has played four games since being recalled Saturday from Triple-A. Outfielder Dustin Fowler, the Yankees' No. 8 prospect, was held out of both games on Wednesday with Scranton/Wilkes-Barre and could be a candidate to be called up. 
"You have to make adjustments," Girardi said. "I think a lot of times division winners are determined by who survives the injuries the best because it is such a long season, so we've got to survive this."
Bombers bits
• First baseman Chris Carter, who was designated for assignment in a move preceding Austin's promotion, has accepted an outright assignment to Triple-A. Carter, 30, hit .204 with eight homers and 23 RBIs in 167 at-bats this year.
• Yankees right-hander Adam Warren threw 20 pitches in a bullpen session on Wednesday and is eyeing a return to the bullpen when the club returns home Monday. Warren, 29, is on the disabled list with right shoulder inflammation.
• Left-hander Carsten Sabathia is scheduled to throw a simulated game on Thursday. Sabathia, 36, is on the disabled list with a left hamstring strain.
