Andy Murray has turned to Roger Federer's former coach Sven Groeneveld for advice as he looks to build on a straightforward but frustrating first round win at the French Open.

The world number four struggled with the unpredictability of qualifier Eric Prodon's game yesterday but in the end had too much quality for the Frenchman and wrapped up a 6-4 6-1 6-3 victory in an hour and 44 minutes.

Murray has been without a full-time coach since splitting from Miles Maclagan last July and during the clay season has been working mainly with Australian Darren Cahill, who is part of a coaching team available through the Scot's sponsors adidas.

Cahill's television commitments mean he is off limits in Paris so Murray has turned to Swede Groeneveld, who has also coached Greg Rusedski and Ana Ivanovic.

The Scot, who will play Italian qualifier Simone Bolelli in round two, said: "He's got a lot of experience. He's been around so many grand slams. It's more just having that experience around.

"It's not like I'm necessarily talking to him about tactics, but after the match I was just explaining how I was feeling, and he knows that it's normal not to feel your best in the first match, that it's tricky conditions, and the most important thing is to get through.

"It's just having someone that's been there that, if I need the advice, he can give it to me."

Murray, meanwhile, confirmed he will definitely play in Great Britain's Davis Cup match against Luxembourg in Glasgow in July.

The Scot's appearance, his first in the competition since September 2009, means the result should be a formality, with Luxembourg number one Gilles Muller the only obstacle.

Murray said: "I know Gilles very well. I used to practise with him a lot in Barcelona and used to get on very well with him. He plays well on indoor hard courts.

"I think it's a match that we should definitely win. If we don't, I'd be very disappointed, but he's going to make it difficult because he's a tough player."

After Heather Watson's victory yesterday ended a run of 17 years without a British winner in the first round of the women's singles, Elena Baltacha matched the teenager by beating rising American star Sloane Stephens 7-5 6-2.

Not since John Lloyd, Jo Durie and Anne Hobbs in 1984 have three British players reached the second round, and Baltacha was thrilled to continue her encouraging clay-court form.

The 27-year-old said: "I've got to say that was the most satisfying win I think of my whole career.

"I'm so happy I listened to my coach Nino (Severino), because he was trying to persuade me to have a proper clay season for the last couple of years, and I actually always resisted just from not having the confidence from not winning many matches on the clay."
