Matt Thornton (elbow) played catch Thursday without incident. "The MRI was extremely over the top precautionary," said Thornton. "It was the back side of the elbow and the ligaments are fine. It's probably just tendinitis I'm guessing, whatever you want to call it. I'll get that area under control and move forward. I'm fine." Thornton expects to play catch again before progressing to a bullpen session and eventually live batting practice. He's aiming to make his Cactus League debut on March 5, so he should have plenty of time to get ready for Opening Day.
