Former world no. 3 and three-time Grand Slam champion Stan Wawrinka is back inside the top-20 for the first time since March last year following a great result in Paris and 19 wins so far in 2019. The Swiss was forced to delay the start of grass season, withdrawing from Stuttgart and making preparations for return at Queen's next week.
Also, Wawrinka has added a new name to his coaching staff, with Daniel Vallverdu joining the squad for the grass swing. Vallverdu is a former coach of Andy Murray, Tomas Berdych and Grigor Dimitrov with whom he worked from July 2016 to this May, achieving some great things together.
In 2017, the Bulgarian claimed the first Masters 1000 title in Cincinnati and won the ATP Finals in November, becoming world no. 3 and hoping for more of the same in the years to come. Instead of that, Grigor lost his form completely in 2018 and is yet to find it again, barely staying in the top-50 and never reaching the semi-final after Monte Carlo last year!
Vallverdu will now turn his attention to Wawrinka who has gained 47 positions on the ATP list so far this year, kicking off the season with a 3-3 score and taking 16 of the next 22 matches, playing in the final in Rotterdam in February and advancing into the last eight in Madrid and at Roland Garros.
The Swiss is yet to lift the title on grass, losing s-Hertogenbosch final in 2013 and hoping for a strong run with the coach who already worked with excellent grass-court players in the past. "I am pleased to announce that I will collaborate with Daniel Vallverdu for the up and coming grass court season.
He will be an addition to my team and I’m excited to learn from his extensive experience and knowledge in the world of tennis!"
