Cubs say DeRosa kept overnight at hospital

MESA, Ariz. -- It turns out Cubs second baseman Mark DeRosa spent Saturday night into Sunday at a Mesa hospital after complaining of a rapid heartbeat during drills Saturday morning.

Originally, the Cubs said DeRosa had been sent home Saturday evening. However, that turned out to be bad information, and the Cubs said DeRosa remained overnight for precautionary reasons.

The Cubs said they expect DeRosa to be released from the hospital sometime Sunday and that he'll be examined by a cardiologist and Cubs doctors Monday.

Cubs management stressed DeRosa's situation is not life-threatening and that it's possible he could be back on the practice field by midweek.

DeRosa was taken by ambulance to Banner Desert Medical Center about 12:30 p.m. Mountain Time Saturday after complaining of a rapid heartbeat. An EKG performed at the Cubs' Fitch Park facility was not normal, and the Cubs placed a 911 call. The Cubs said Sunday that DeRosa was given medication to put the heart back into proper rhythm and that the medicine was effective.

DeRosa, who turns 33 Tuesday, has experienced similar problems for many years, according to the Cubs.
