World no. 21 Stan Wawrinka will skip the penultimate Masters 1000 event of the season in Shanghai, still struggling with a knee injury. The 34-year-old has not played since the quarter-final of the US Open, skipping St. Petersburg and Tokyo and still not feeling ready to compete again.
Wawrinka had played in nine of the first ten editions of the Shanghai Masters since 2009, earning 12 victories and competing in the quarter-final in 2013 and 2015 to Rafael Nadal, taking just three games in that second clash against the Spaniard that Rafa grabbed in 64 minutes.
Stan had to skip Shanghai in 2017 due to that knee injury that sent him away from the top-200 in June last year, working hard on the comeback and securing the place in the top-20 again after 12 months. Kicking off 2019 season from outside the top-60, Stan manifested positive signs in Rotterdam where he played for the title, suffering early losses in the next couple of events before advancing into the quarter-final in Madrid and Roland Garros, losing to Roger Federer in four tight sets after more than three and a half hours.
Stan claimed only four victories at Queen's, Wimbledon, Montreal and Cincinnati, returning stronger at the US Open where he defeated Novak Djokovic in the fourth round following retirement of world no. 1 due to a shoulder injury.
In the battle for the semi-final, a former champion lost to Daniil Medvedev in four sets, taking the third set before the Russian stormed over the finish line in the fourth to stay on the title course. After Shanghai, Stan should play in Antwerp, Basel and Paris if he recovers in time, hoping for a strong finish of the season and even better results in 2019 if he leaves injuries behind him.
