[3] For the better part of the next 39 seasons, Monahan was entrusted to care for and tend to the injuries of players from Reggie Jackson to Derek Jeter.

[6] He had surgery in January 2010, and underwent radiation therapy for several months, which forced him to miss his first spring training in 48 years.

[8] On May 11, 2011, the Yankees announced that Monahan would retire following the 2011 season,[9] and on June 26, 2011, the team honored him at their annual Old-Timers' Day.

After retiring from the Yankees, Monahan moved from his home in Hackensack, New Jersey to Mooresville, North Carolina, where he now works as a consultant for Hendrick Motorsports.
