Cubs second basemen / utility player Mark DeRosa was hospitalized on Saturday with an irregular heartbeat.  DeRosa was fielding groundballs at second base when he became short of breath and after being checked out by the trainer, he was taken off the field on a stretcher even though he was sitting up.

DeRosa stayed Saturday night in the hospital while tests were being run, and then was released on Sunday.  He shouldn’t miss much time with team, and will probably be back later in the week but will be monitored very closely.
