French Open 2015: Andy Murray through to round two after beating Facundo Arguello

Andy Murray is comfortably through to the second round of the 2015 French Open following a straight sets win over Facundo Arguello.

World number four Murray, who is unbeaten on clay this year following victories at the Munich Open and Madrid Masters tournaments, had no trouble dispatching of the Argentine qualifier 6-3, 6-3, 6-1 in under two hours.

"I was nervous today," Murray, who faces either Vasek Pospisil or Joao Sousa next, said after registering an emphatic win.

"Always the first round of the major competitions are tough and it was quite windy and difficult conditions at the start.

"I was a little bit nervous at the start but I like that, it shows that you care and want to do well."

Elsewhere for the British contingent on day two at Roland Garros, Heather Watson progressed after beating Mathilde Johansson 6-4, 7-5 and will now play Sloane Stephens after the 22-year-old triumphed over compatriot Venus Williams 7-6, 6-1.

Johanna Konta fell to Denisa Allertova and Slovenian-born Aljaz Bedene lost to Dominic Thiem but there was a first ever grand slam win for Kyle Edmund, who outlasted home favourite Stephane Robert in a five-set thriller.

He will meet Nick Kyrgios in round two.
