Yankees manager Aaron Boone is stepping away from the team immediately to receive a pacemaker, the club announced Wednesday afternoon.

“As many of you know, I underwent open-heart surgery in 2009, and I wanted everyone to understand where I’m at regarding the procedure that’s taking place today,” Boone said in a statement.

“Over the last six-to-eight weeks I’ve had mild symptoms of lightheadedness, low energy and shortness of breath. As a result, I underwent a series of tests and examinations in New York prior to the beginning of spring training, including multiple visits with a team of heart specialists. While the heart checkup came back normal, there were indications of a low heart rate which, after further consultations with doctors in Tampa, necessitates a pacemaker.”

“The thoughts of the entire organization are with Aaron and his family as he undergoes this procedure and takes the time he needs to properly heal,” said Yankees managing general partner Hal Steinbrenner in a statement. “Aaron leads our players, coaches and staff with a rare combination of work ethic, intelligence and a genuine concern for others. Our only priority at this time is Aaron’s health and well-being, and we will support him in every way throughout his recovery.” Boone says he undergoes routine exams every few years to monitor his status. Bench Coach Carlos Mendoza will take over as the interim manager until Boone returns.
