From the AP, via AJC.com:
Mesa, Ariz. — Second baseman Mark DeRosa was taken out of the Chicago Cubs' spring training complex on a stretcher and transported by ambulance to a hospital Saturday after experiencing an irregular heartbeat.
DeRosa, a former Braves player, was sitting up as he was wheeled out of the Fitch Park complex. Some of his teammates were still in the field winding up a day of workouts.
Poor DeRo. He's one of the few former Braves I follow closely, and I hope he gets well soon. Kisses, DeRo my hero!
ETA: Sunday night. DeRo's out of the hospital but will need more evaluation. If I find out this was greenie-related, sweets, you'll be off my list. (Really, though. Get well soon.)
