NEW YORK :World number one Novak Djokovic sailed into the third round of the U.S. Open and moved a step closer to achieving a calendar year Grand Slam while 2019 women's champion Bianca Andreescu extended her unbeaten run at Flushing Meadows to nine matches.
Djokovic beat Tallon Griekspoor 6-2 6-3 6-2 and the top seed said he had found his groove after dropping a set in his first round victory over the unheralded Holger Rune.
"I'm very pleased with the level of my tennis. All is going in the right direction," said Djokovic, who meets Kei Nishikori in the next round.
Canada's Andreescu, who has never lost a main draw match at Flushing Meadows, was down a break four times against American Lauren Davis but won the crucial points to register a 6-4 6-4 victory.
"I feel like I have a commitment now to keep it straight sets every match, which adds a bit of pressure on my shoulders," Andreescu said. "Honestly tennis is super chaotic and I never try to play three sets."
Her compatriot Denis Shapovalov was in fine form as he defeated Roberto Carballes Baena 7-6(7) 6-3 6-0 in a match that quickly unravelled for the Spaniard, who beat Shapovalov at last year's French Open.
"I obviously definitely wanted to get my revenge," Shapovalov joked.
Last year's runner-up Alexander Zverev needed only 74 minutes to thrash Spain's Albert Ramos-Vinolas 6-1 6-0 6-3, wrapping up the match with three consecutive aces.
Women's top seed Ash Barty saw off Danish 18-year-old Clara Tauson 6-1 7-5 while fourth seed Karolina Pliskova saved a match point to beat American Amanda Anisimova 7-5 6-7(5) 7-6(7) with a tournament record 24 aces.
