WATCH: Derek Jeter Takes Field at Fenway Park in Ceremony

Red Sox fans have rooted against Derek Jeter for 20 years, but Fenway Park was packed Sunday afternoon with fans wishing Jeter well and celebrating the 20-year career that came to an end when the Sox hosted the Yankees.

The Captain got a rousing ovation from the crowd and from both dugouts when he took the field.

Pete Frates, the former Boston College baseball captain and inspiration behind the Ice Bucket Challenge, was among the guests who the Sox brought in to honor Jeter.

The Sox showed a video clip of Jeter taking the challenge on the center field jumotron, then introduced Frates, who wheeled himself out onto the field to greet Jeter to a standing ovation.

The ceremony was a star-studded affair that also included appearances by former Red Sox captains Carl Yastrzemski, Jim Rice and Jason Varitek, Bruins legend Bobby Orr, and former captains Paul Pierce of the Celtics and Troy Brown of the Patriots.
