Russian third seed Daniil Medvedev faced little resistance from Federico Delbonis of Argentina in a 6-1, 6-2, 6-4 win on Tuesday to ease into the second round of the US Open.

The 24-year-old Medvedev, who lost to Rafael Nadal in last year's final, faced just two breakpoints in the entire match -- in his first service game of the second set -- while breaking his opponent on five occassions.

In the first meeting between the two players, Medvedev sealed victory when his 79th-ranked opponent sent a return into the net in the final match of the evening on Arthur Ashe Stadium court.

In his second-round match the Russian will meet Australian Christopher O'Connell, who earlier defeated Laslo Djere of Serbia 4-6, 6-4, 7-6(2), 6-4.

- Thiem through as Munar retires -

Austrian second seed Dominic Thiem advanced to the second round of the US Open when Spaniard Jaume Munar retired after dropping the first two sets.

Thiem, who reached his third Grand Slam final at this year's Australian Open where he lost to Novak Djokovic, was leading 7-6(6), 6-3 when Munar ended the match.
