Dominic Thiem

Dominic Thiem ended six years of Grand Slam frustration against Rafa Nadal on Jan. 29 with a seismic 7-6(3) 7-6(4) 4-6 7-6(6) upset that booked his maiden Australian Open semi-final and rocked the old guard of men's tennis.

Few players have looked capable of breaking the stranglehold Rafa Nadal, Roger Federer and Novak Djokovic have had on Grand Slams over the last 15 years but if anyone can end their reign in 2020 it is likely to be Stefanos Tsitsipas.

Stefanos Tsitsipas has beaten Dominic Thiem in 3 sets to win ATP Finals title.

Tsitsipas rallied to beat Thiem 6-7 (6), 6-2, 7-6 (4) on Sunday to become the youngest ATP Finals champion in 18 years and collect the biggest title of his career.

Stefanos Tsitsipas kept his nerve in the key moments to beat six-time champion Roger Federer 6-3, 6-4 on Saturday and reach the final of the season-ending ATP Finals.

Tsitsipas saved 11 of 12 break points and took advantage of an error-filled performance from Federer, who continually put his opponent under pressure only to come up short when it mattered.

Rafael Nadal staged another comeback to stay in contention for a semifinal spot at the ATP Finals.

The top-ranked Spaniard still needs help from Daniil Medvedev to avoid an early exit.

In their major 49th duel, Roger Federer beats Novak Djokovic after 72 minutes of play with a 6-4, 6-3 win.
Federer finished second in Group Bjorn Borg, behind Austrian Dominic Thiem, who beat both Federer and Djokovic earlier this week.

Grigor Dimitrov has climbed seven positions up in the world rankings and is already the 20th in the world. The progress of the Bulgarian is due to his wonderful performance at the Paris Masters, where he reached the semifinals.

Dominic Thiem withstood 30 aces from big-serving Canadian Milos Raonic to win 7-6 (5), 5-7, 6-4 on Wednesday and reach the third round of the Paris Masters.

The two-time French Open runner-up also saved nine break points out of 10, and then broke Raonic for the first time in the ninth game of the deciding set before serving out the match.

Stefanos Tsitsipas accused a US Open chair umpire of having a bias against him during a tirade in which he told the official, "You're all weirdos!"

Tsitsipas told Damien Dumusois that the cause of his bias was "because you're French probably and you're all weirdos!"

Grigor Dimitrov achieved his first victory since Roland-Garros, after dramatically overtaking Steve Johnson in the first round of the ATP 250 Hard-court Tournament in Los Cabos, Mexico.

After four consecutive defeats, Dimitrov suffered success after 2 hours and 28 minutes of play, thanks to two won tiebreaks - 7: 6 (4), 4: 6, 7: 6 (5).
