Matt Thornton played catch on Thursday without incident and the White Sox are breathing a little easier.

The veteran reliever reported to the coaching staff he feels fine after he missed the past two days with soreness in his left triceps. An MRI taken on Tuesday showed Thornton has tendonitis in his left elbow but no structural damage.

White Sox manager Robin Ventura said Thornton, who tied a career-high with 74 appearances last season, is scheduled to play catch on Friday.

“I think the concern level has gone down, Ventura said. “We’re not in the orange area anymore. I think it would be yellow. We’re going to go to yellow at this point.”

The plan calls for Thornton to take it easy this spring. He didn’t begin a throwing program until January and isn’t expected to overdo it when it comes to game action this spring. Thornton thinks the inflammation in his elbow is the result of a long first week of work and has described it as a minor concern.

Thornton isn't scheduled to appear in a Cactus League game until March 5.

“I’m worried about April 1. That’s all I care about,” Thornton said. “I don’t care if I get two or three games in and somehow something else happens. I get two or three games in and I’m ready April 1. If April 1 comes in jeopardy, believe me you guys will know and I’d be worried then. … It’s no big deal.”
