The US Open begins with a bang on Monday with a monster 64-match schedule. Among the names are world No. 1s Rafael Nadal and Simona Halep plus many more champions including US Open winners Serena and Venus Williams, Juan Martin del Potro, Andy Murray, Svetlana Kuznetsova, Sloane Stephens and Victoria Azarenka.
With Louis Armstrong debuting a roof, the Ashe schedule has been reduced from three matches during the day to two, thus almost virtually assuring an on-time 7pm start to the night schedule while also cutting down on the congestion outside of Ashe as night ticket holders wait to get in.
And day one on Ashe will feature four US Open past champions. Louis Armstrong had five Slam champions with four of them winning in New York.
Also on Monday, on Grandstand Denis Shapovalov meets fellow Canadian teen Felix Auger-Aliassime who is making his Grand Slam debut.
