Like with the Chengdu Open; most of the big names involved are in Laver Cup action currently, those include the aforementioned names of Kyrgios and Tsitsipas.
Lucky enough for Tsitsipas; he has a bye so will not play for a few days anyway. Gael Monfils, Borna Coric and Roberto Bautista Agut have also received byes due to their seeding.
Kyrgios on the other hand will start his campaign against Andreas Seppi; who himself has been getting in game time on the Challenger Tour over in America after his US Open loss to Grigor Dimitrov.
Andy Murray will also be involved continuing his comeback; he will face Tennys Sandgren again like he did at the Winston-Salem Open where he lost out. Alex de Minaur is also involved; he could face the winner.
