Bob Bryan and Mike Bryan announced today that they will retire from professional tennis after the 2020 US Open.

The retirement of the Bryan brothers, the greatest doubles team of all time,  will mark the end of a remarkable run. They  have been playing on the tour for 21 years. The retirement of the 41-year old twins is not surprising considering their age and ranking.  The Bryan brothers ended 2019 ranked 27th in the world.

The Bryan brothers have captured an Open Era record of 118 titles careers, including all four Grand Slams, all  9 ATP Masters 1000s,  4 WTF  ATP Finals titles and an Olympic gold medal.  They won more than 1,100 matches in their career, with a winning percentage over 75. For more than a decade, the  Bryans won the ATP Tour Fans’ Favorite Team award.

The Bryan brothers spent 438 total weeks and ended 10 seasons as the No. 1 ranked team in the world.

“We wanted to see if we wanted to keep going,” Mike told the Tennis Channel Live, “and we’ve decided that 2020, at the [US] Open, we’re going to shut it down. One more season—and we’re excited for it.”

“Obviously, very difficult decision, big decision—we’ve been on tour for 21 years, more than half our lives,” said Bob Bryan. “Tennis is in our blood, so it feels like a part of us is dying.”

Slovakia’s Dominika Cibulkova announced her retirement from professional tennis at an event in her home town of Bratislava.

30-year old Cibulkova reached a career-high ranking of World No. 4 in 2017.  That was the highest ranking ever achieved by a player from Slovakia. She won eight titles and earned over $13 million during her career

In 2014, Cibulkova became the first Slovak woman to reach a Grand Slam singles final, before losing to  China’s Li Na at the Australian Open. She was also a semifinalist at Roland Garros in 2009.  She reached the quarter-finals at Wimbledon three times.
