For sure he made me better,” Wawrinka said.Since that loss in Paris, however, it has virtually been business as usual.He had beaten Andy Murray and Nadal to get to the final but Wawrinka hadn’t read the script, his 60 winners — most fired off the backhand — proving hammer blows to the Serb.In 2014, Wawrinka won a five-set quarter-final on his way to a first Grand Slam crown at the Australian Open, beating Rafael Nadal in the final.Last year, Djokovic saw his hopes of completing a career Slam crushed in four sets by the Swiss in the French Open final.Wawrinka trails 19-4 in his career meetings with Djokovic, who is chasing a third New York crown and 13th major.“He’s a big match player.“The matchup has always been interesting to see because the way we are playing.

He can be very dangerous for everybody.But the 31-year-old Swiss has derailed the Serb before on the biggest stage.”Djokovic was left wondering what had hit him at Roland Garros in 2015.Stan Wawrinka will summon the spirit of his epic Grand Slam battles with Novak Djokovic in a bid to sweep past the world number one and capture a first US Open title on Sunday.
