He is in the clay-court form of his life, but Andy Murray admitted to feeling nervous as he kicked off his bid to win a first French Open title with a straight-sets victory over Argentina's Facundo Arguello.
Murray is yet to be defeated since marrying long-term girlfriend Kim Sears in April, with victory over world No.137 Arguello making it 11 wins in a row on clay for the British No.1.
Sears was courtside to watch her husband for the first time since their wedding and there was little danger of her witnessing an upset on Court Philippe Chatrier, as Murray took just one hour and 44 minutes to wrap up a 6-3 6-3 6-1 victory.
Speaking in his post-match interview, third-seeded Murray admitted to feeling a little tense on court, but insisted that merely proved how much he wants to win in Paris.
"I was nervous today," he said. "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."
Despite the nerves, Murray has been red hot on clay in the build-up to the year's second grand slam, claiming his first title on clay in Munich earlier this month before backing that up with victory over Rafael Nadal at the Madrid Open.
And there was little sign of the fatigue that caused him to pull out of the Rome Masters almost a fortnight ago as he set about bulldozing his 22-year-old opponent off the Roland Garros clay.
Murray's game was not without its wobbles, particularly in a first set which saw a swirling wind affect his rhythm. The Scot initially raced to a 3-0 lead before allowing Arguello to level at 3-3. But the fight-back was to be short lived as Murray won the following three games to close out the first set in 40 minutes.
Arguello made a better attempt at keeping pace with his more experienced opponent in the second set, pushing him to 3-2 before Murray upped the pace to earn three set points and a look at the second round.
By the third set, Murray was at his dangerous best, firing off a series of rapid service games and breaking Arguello with ruthless ease before claiming victory with the second of three match points.
After securing his place in the second round, where he will face either Vasek Pospisil or Joao Sousa, Murray grinned when asked if it was more difficult to persuade Sears to marry him than win two titles on clay.
"She'd put up with me for nine-and-a-half years so it was probably about time I proposed," he said. "I'm glad she said yes. My tennis since we got married has been good and I hope I can keep that up."
