US Open 2017: Rafael Nadal takes first two sets against Dusan Lajovic

The world number one was broken by his Serbian opponent in the fourth game of the first set to trail 3-1, but restored parity against the world number 85 under the roof at a rain-hit Arthur Ashe when he broke Lajovic to love to level at 5-5.

After both men held serve, then 15-times Grand Slam champion won the breaker 8-6 with a couple of crunching shots sealing the set from 6-6 in the breaker.

Nadal then secured three breaks in the second set to claim the second set.

The pair have met once before with 27-year-old Nadal emerging victorious on clay in the last 16 at Roland Garros three years ago.
