Maintaining his clean record in Grand Slam finals, Stanislas Wawrinka pulled off his maiden US Open title after surprising World No. 1 Novak Djokovic in the Sunday’s title-clash.

Having already won the Australian Open (2014) and the French Open (2015), the 31-year-old Swiss accentuated his competency of performing on the biggest stages as he remains just major shy (Wimbledon, of course) of completing a career Grand Slam.

Djokovic, who was bothered by fitness issues coming into the tournament, looked uncomfortable during the final set before losing 6-7 6-4 7-5 6-3 to the No. 3 seed.

As a result, Wawrinka became only the third man – after Djokovic and Andy Murray – to seal his place in the ATP World Tour Finals that will be held from November 13-20.

Earlier on Saturday, Angelique Kerber won the women’s singles crown following a 6-3 4-6 6-4 conquest of first-time finalist Karolina Pliskova in the summit battle.

This was Kerber’s second Grand Slam triumph after the Australian Open this year. The victory has also propelled her ranking to No. 1 for the first time in her career.
