Pedro Feliciano tweets he's all clear

PORT ST. LUCIE, Fla. -- After undergoing more tests Wednesday, Pedro Feliciano tweeted that he is ready to go -- presumably with baseball activity at camp.

Feliciano had been shut down and was due to wear a heart monitor while doctors investigated a heartbeat irregularity as well as a suspected small "hole" in his heart.

Feliciano's announcement was somewhat unexpected since Sandy Alderson said Sunday that Feliciano would be shut down from baseball activity for two weeks while the southpaw wore a heart monitor.

"The doctors have asked that he be monitored over the next couple of weeks," Alderson said Sunday. "And so he will be hooked up to a telemeter and monitored over the next two weeks. Until that time, we won't really have a diagnosis. With respect to his comment that he has a hole in his heart, I don't think that's clear at this point. I think that what we need to do is wait over the next couple of weeks, until there's a final diagnosis. At this point we don't have a diagnosis, per se. And so it's a little preliminary."
