The higher the CPI, the faster the ball flies after bouncing on the ground. Among the tournaments that have announced the CPI, the US Open 2020 is the one with the highest index.
Among the clay tournaments announcing the CPI, Monte Carlo had the highest CPI (30.3) while Madrid also reached 27.9 at this parameter.
In March this year, USTA announced an agreement with Laykord – a company specializing in ground improvement. Before that, the American Tennis Association cooperated with the DecoTurf company for 40 years.
Laykord pitch is covered with acrylic resin on asphalt or concrete, and resistant to the effects of climate and humidity. The new court surface also helps players move better, reducing injuries, especially in the knee joint area when players change direction.
The US Open 2020 kicks off on August 31, in the absence of spectators on the fields because of Covid-19. This is the first Grand Slam without two defending men’s and women’s singles championships in this century when Rafael Nadal and Bianca Andreescu are both absent.
Some of the other names not participating in the tournament are Roger Federer, Gael Monfils, Fabio Fognini, Stan Wawrinka, Kei Nishikori in the men’s singles, or Ashleigh Barty, Simona Halep, Kiki Bertens, Belinda Bencic in the women’s singles.
The US Open has a coronavirus-infected player
World No. 22 player Benoit Paire was eliminated from the hard court Grand Slam, when positive for nCoV on August 30.
The news that Paire infected with CoV caused confusion for the players who were present at the Billie Jean King stadium complex in New York to prepare for the US Open. The Grand Slam hard court will kick off today, August 31.
Paire passed a medical check before arriving in New York for the Cincinnati Masters last week. But at that ATP 1000, Paire had some unstable health symptoms. He gave up in the first round match against Borna Coric while being led 0-6, 0-1, citing colic.
Benoit Paire foresaw the risks that he may suffer when deciding to go to the US to attend the hardcourt cluster. In early July, the French tennis player said that he has no plans for the US Open because he thinks the trip to New York is too complicated and dangerous.
Paire was originally ranked 17th seed in the US Open. He was the first player to be found infected with coronavirus, among those currently in New York. Last week, Guido Pella and Hugo Dellien lost their chance to attend hard court competitions in the US, when their fitness coaches were virus-positive.
