(CNN)Bob and Mike Bryan, the most decorated doubles partnership in tennis history, will retire at the end of next season.
The 41-year-old twins, who have amassed a record 118 titles including 16 grand slams, will call time on a glittering 21-year career at their home US Open in September 2020.
"Mentally, physically, we wanted to get together, reflect on our career, and then make a big decision," Mike told the Tennis Channel. "We wanted to see if we wanted to keep going and we decided that 2020 at the Open, we're going to shut it down. So, one more season and we're excited for it."
Bob added: "It has truly been a magical ride. However, we want to end this great ride while we're healthy and we can still compete for titles. We've been on tour for 21 seasons, more than half our life.
"Tennis is in our blood. A part of us it feels like is dying. But we're really clear about this decision. It's going to be great to have a finish line."
