PARIS, May 30 (Reuters) - World number one Andy Murray defied expectations that he would struggle at this year's French Open by beating Russia's Andrey Kuznetsov 6-4 4-6 6-2 6-0 in the first round on Tuesday, but day three at Roland Garros still served up plenty of other upsets.
Top seed Murray, who came into the tournament in poor form and suffering from illness, saw out a mostly regulation win over his 73rd ranked opponent -- the perfect tonic to settle the Scot's nerves ahead of tougher tests to come.
In the women's draw, Britain's Johanna Konta fell at the first hurdle for the third year in a row after suffering a shock 1-6 7-6(2) 6-4 defeat by unseeded Taiwanese Hsieh Su-Wei.
Spanish veteran Fernando Verdasco ousted highly-rated German youngster Alexander Zverev -- seeded ninth in Paris after winning the Italian Open -- in another shock result when their match resumed on Tuesday after being suspended the day before.
The day's other highlights included Argentine Juan Martin del Potro's successful return to Paris after a five-year hiatus. Del Potro, whose career has been plagued by injury, thrashed compatriot Guido Pella 6-2 6-1 6-4.
Third seed Stan Wawrinka started slowly against Slovak qualifier Jozef Kovalik, but the Swiss did enough to win the rallies that mattered and ultimately emerged victorious in a shade under two hours.
Australian Nick Kyrgios kept his emotions in check to outclass Germany's Philipp Kohlschreiber, while women's third seed Simona Halep moved smoothly into the second round with a 6-2 6-3 win over Slovakia's Jana Cepelova.
Halep came close to pulling out of the tournament after tearing ankle ligaments less than two weeks ago, but showed no ill effects from the injury and will face Germany's Tatjana Maria in round two.
