Defending champion Novak Djokovic has lost at the U.S. Open one night after Carlos Alcaraz did.

How much do you know about Wimbledon.

Andy Murray was pleased with the result but not happy about the circumstances after finishing an Australian Open victory after 4 a.m. His marathon raised anew the issue that tennis has shown it is that rare sport where folks sometimes need to play all night.

Canada has won its first Davis Cup tennis title, beating Australia behind victories from Denis Shapovalov and Felix Auger-Aliassime.

Roger Federer is leaving tennis after more than two decades as a pro player with a style that rarely betrayed the effort behind his mastery.

Roger Federer has announced his retirement at age 41 after participating in some of the most memorable matches in the history of Grand Slam tennis.

Tennis pro Nick Kyrgios says he had “suicidal thoughts” and dealt with depression and abuse of drugs and alcohol in the past.

To some, it seemed a cloud had been lifted from the Australian Open.

Djokovic’s Australian Open championship last month gave the 33-year-old from Serbia 18 Grand Slam singles trophies. That would make Medvedev the first man other than Federer, Nadal, Djokovic or Andy Murray to be first or second since International Tennis Hall of Fame electee Lleyton Hewitt was No. 1, followed by Australian Open champion Naomi Osaka, Simona Halep, Sofia Kenin and Elina Svitolina.

Nadal's withdrawal from the ABN AMRO World Tennis Tournament was announced Thursday. Instead, third-ranked Daniil Medvedev, the runner-up to Novak Djokovic at the Australian Open, will take the top spot in the seedings. The 34-year-old Spaniard then was able to participate in the year's first Grand Slam tournament, which began Feb. 8.
