A concern that led manager Mike Matheny to remove Adam Wainwright from his shutout after the seventh inning Tuesday is the same reason the Cardinals sent their ace back to St. Louis on Wednesday for a battery of exams.

Wainwright had an MRI scan taken of his right elbow and several other tests to determine the severity and location of soreness in his pitching arm. He also received an anti-inflammatory shot to attack the irritation. The club described his next start as uncertain until it’s clear the irritation has been addressed.

The club was also encouraged the damage was not around his repaired ligament.

“Given his past history it’s important to underscore that the (Tommy John surgery) ligament is completely fine,” general manager John Mozeliak said. “We know the importance of him to our rotation. … We want to stay extra cognizant of what he needs to stay in the rotation and be healthy from here. We are going to be cautious with this.”

The shot that Wainwright received requires a couple of days of inactivity, so the club won’t know of Wainwright’s availability for his start Monday until gauging his recovery. The team could use today’s off day to rearrange the rotation and buy Wainwright as much as two extra days of rest.
