US Open: Roger Federer and Rafael Nadal kick off campaigns

Roger Federer and Rafael Nadal will be in action on Tuesday on the second day for the 2017 US Open tournament. 

Federer closes proceedings against American Frances Tiafoe on centre court, which was equipped with a roof last year that could prove helpful as rain might disrupt the action at Flushing Meadows. World number one Nadal will face Serbia's Dusan Lajovi. 

A year ago, few would have bet Roger Federer and Rafa Nadal would be the top contenders at the 2017 U.S. Open, yet the Swiss maestro and the Spanish juggernaut start their campaign with the favourites tag on Tuesday.

Federer and Nadal have won the first three grand slam titles of the season as they came back to prominence with a bang, and nothing suggests their first-round opponents, Tiafoe and Lajovic, will bother them.

Women's world number one Karolina Pliskova of the Czech Republic will get things going on Arthur Ashe against Poland's Magda Linette before defending champion Angelique Kerber takes on talented Japanese Naomi Osaka.

Canadian Eugenie Bouchard, who is suing the U.S. Tennis Association for negligence after she sustained a concussion in a fall on the locker room's floor in New York last year, takes on Russian Evgeniya Rodina on Grandstand.

Former champion Juan Martin Del Potro, the 24th seed, is also in action, against Swiss Henri Laaksonen.
