Yankees manager Aaron Boone underwent surgery to put a pacemaker in place on Wednesday at St. Joseph's Hospital in Tampa, Florida. The procedure went as expected, and Boone was recovering Wednesday night, according to the Yankees. Boone took an immediate leave of absence from the team, the Yankees announced earlier in the day.

Boone released the following statement through the club on Wednesday: 

"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. 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.
