The Rolex Shanghai Masters opens its main draw with Round 1 on Grandstand 2 in Shanghai, as Pablo Carreno Busta faces Mariano Navone Thursday just after 1:30 AM EDT. The opening-round matchup draws the tournament’s first scheduled contest on the assigned court. Both players begin from the same starting point in a men’s singles field that resets each Round 1, with the Grandstand 2 assignment dictating the early flow before later sessions move to the larger venues.
