Manager Ned Yost said the team does not believe the issue with Infante's elbow concerns his ligament.
"It could be a bone spur that chipped or broke loose and is causing inflammation," Yost said. "We just don't know, so we'll get it checked out. We'll see if maybe a [cortisone] shot is warranted. We'll find out."
Infante said the elbow discomfort is nearly on the same level as what he experienced last spring at this time.
"Same thing," Infante said. "Just doesn't feel right."
Yost defended his training and medical staff when asked why Infante's issue wasn't resolved in the offseason.
"Every guy in that locker room has some [injury] issue," Yost said. "You have 50 or 60 or 70 percent of the guys who have some kind of elbow issues. That's baseball.
"Our medical people are the best in the business, and they have monitored [Infante's] situation all offseason. No one dropped the ball."
