Paul Maintains Momentum In Moscow

American will next play two-time Moscow champion Cilic

Tommy Paul reached the fourth round of an ATP Masters 1000 event for the first time in Indian Wells, and the American has maintained his momentum in Moscow.

The World No. 54 advanced to the second round of the VTB Kremlin Cup on Tuesday with a 7-6(7), 7-5 win against Swede Mikael Ymer.

Paul broke the Next Gen ATP Finals alumnus' serve four times and won 44 per cent of his return points to move on after one hour and 57 minutes. The 24-year-old, who upset Andrey Rublev in the California desert, will next play two-time Moscow champion Marin Cilic, who beat Damir Dzumhur in three sets on Monday.
