Chicago Cubs starter Carlos Silva is on the disabled list while he recovers from an abnormally rapid heart beat (presumably more rapid/abnormal than when a chubby guy jogs into KFC to nail down the last Family Feast served that day). For now, things are still in the evaluative stage, but Silva has started throwing.

Cubs pitcher Carlos Silva was able to play catch Wednesday, but he is still undergoing tests to determine what caused the abnormal heart rate that forced him out of his last start.

Silva was pulled Sunday after facing four batters in Colorado, spent the night at a Denver hospital and flew back to Chicago on Monday. He was being examined by cardiologist Mark Upton.

Silva was placed on the disabled list Monday to give him time to get treatment.

Hopefully, for both Silva’s sake and the Cubs’ sake, doctors are able to pin down what the issue is.
