Murray and Heather Watson both recorded straight-set wins while 20-year-old Kyle Edmund came??from behind to win in five against France’s Stephane Robert.
It is the first time since 2011 three British players have come through the??first round in Paris but Murray called for some perspective on the achievement.
“It depends on what is ‘doing well’,” Murray said.
“Winning a couple of rounds at a French Open for us, for the UK, is good but, France or Spain or the Argentinians, I don’t think they look at it??and would be very impressed by that.
“A lot of the other nations have multiple players going deep into the Grand??Slams and ultimately that’s where you want to try to get to.
“Tennis in the UK is obviously a big sport, there’s a lot of money invested in??it, so you want to try to get as much depth as possible.
“For us it’s great, but I don’t think the other countries are looking at it??and saying, ‘I think it’s great you have two or three players in the second??round of a Grand Slam’.”
Britain began the day with five players in the first round but Johanna Konta??lost in three sets to Czech Denisa Allertova while Aljaz Bedene was beaten in??four by Austria’s Dominic Thiem.
“I saw a little bit of Bedene and Thiem’s match before I went on,” Murray??said.
“It seemed like it was a pretty good match. Thiem is obviously a tough??opponent on clay.
“It’s obviously good that Heather has won. It’s obviously nice – the more British players in the tournament the better.
“The last few years there has been lots of doubles guys around, which is nice,??but more players in the singles, it’s obviously good.”
Murray took less than two hours to beat Argentinian qualifier Facundo Arguello??6-3 6-3 6-1 as he bids to win his first title at Roland Garros.
The Scot was never at his fluent best but he rarely needed to be and he will??now play either Canada’s Vasek Pospisil or Portugal’s Joao Sousa in round two.
“It was definitely tricky,” Murray said.
“I felt like when I got some good depth into his backhand, I was able to??dictate a lot of the points.
“When he hit the first ball with his forehand, he was able to make me run and??do a lot of moving. He’s a tough, tough player.”
