Reigning Australian Open champion, Stanislas Wawrinka, got off to a stunning start at the ATP World Tour Finals in London after the Swiss demolished Czech Republic’s Tomas Berdych 6-1, 6-1 at the infamous O2 Arena on Monday.

As the scoreline reflects, Wawrinka dominated the match at length, winning 95 per cent of his first-serve points besides converting 5 off the 9 break-point opportunities.

“For me, when I play against him (Berdych) it’s always tough, but I can always find a solution. I’m really happy with the way I handled the situation,” Wawrinka was quoted as saying by BBC Sport.

Interestingly, it came out to be Wawrinka’s most emphatic victory against a top 10 player in his 34 career-wins.

In the other Group ‘A’ match on Monday, top seed Novak Djokovic wasted no time as he thrashed U.S. Open champion, Marin Cilic, 6-1, 6-1.

Earlier on Day 1, Roger Federer had defeated Milos Raonic, while Kei Nishikori had pulled off a stunner against Andy Murray in Group ‘B’ matches.
