• Willie McGee, a special assistant to Mozeliak, has arrived in Florida and spent Tuesday in uniform as a guest instructor for the Cardinals. Though his 18-year playing career ended in 1999, McGee has remained a regular presence in Jupiter, Fla., each spring.
• Matheny said that he expects to announce his early spring rotation plans on Wednesday. Matheny has only confirmed that Carlos Martinez and Tyler Lyons will pitch in Friday's Grapefruit League opener.
• Carson Kelly has made enough progress in his conversion from third baseman to catcher that the Cardinals are not ruling out giving him an opportunity to appear in a Grapefruit League game. Kelly, 19, was invited to Major League camp so that he could get additional instruction -- particularly from Matheny and veteran catcher Yadier Molina -- and has opened eyes in the process.
"The camp has been a success for him already with the things that he has been able to do," Matheny said of Kelly, who began the position tranisition in September. "What's probably been as impressive as anything is his willingness to go and learn. He follows Yadi like they're attached at the hip, and that's something that he wanted to do and was endorsed by Yadi. How can you put a price tag on what that means to a young catcher?"
