No problems for Shapovalov and Paire
Straight-set wins took Denis Shapovalov and Benoit Paire, the top two seeds, into the third round of the Winston-Salem Open.
Paire, the number one seed, clinically dismissed Prajnesh Gunneswaran 6-3 7-5 with his 14th ace on match point confirming the victory.
That avenged the Frenchman's defeat to the 29-year-old at Indian Wells back in March and sets up a third round meeting with fellow countryman Ugo Humbert, who was a 3-6 6-3 6-2 winner over American Bjorn Fratangelo.
Second seed Shapovalov cruised to a 6-2 6-4 victory over American Tennys Sandgren, Andy Murray's conqueror from the night before.
The hard-hitting Canadian will next face Serbian teenager Miomir Kecmanovic in the round of 16 on Wednesday.
Elsewhere, Lee Duck-hee lost to rising Polish player Hubert Hurkacz 4-6 6-0 6-3 and Andrey Rublev, who stunned Roger Federer at the Cincinnati Masters, won two matches on Tuesday after a rain delay and will meet big-serving American Sam Querrey in the next round.
