The couple were married in a smaller ceremony aboard a yacht and then hosted friends, family and associates, including Commissioner Bud Selig, for a festive reception Saturday featuring the rock band Maroon 5.
The Boston Globe reported Sunday the guest list also included Boston Celtics Chief Executive Officer Wyc Grousebeck and managing partner Steve Pagliuca.
The newspaper said security was tight for the affair. Stadium workers were told to leave their cell phones at home and guests were requested not to take pictures on their phones, either.
The Red Sox themselves were not in attendance. They were on the road in Atlanta Saturday.
The couple have been an item around Boston the past two years. He is 60 while his new wife just hit 30.
