British number one Johanna Konta battled into the second round of Wimbledon with a 7-5 6-2 victory over Romanian qualifier Ana Bogdan.
The 19th seed is the best hope for home success in the singles after reaching the semi-finals of the French Open.
She has not yet shown the same form on grass, losing relatively early in Birmingham and Eastbourne, and did not have things all her own way against 132nd-ranked Bogdan on Court One.
It was attack against defence, with Konta hitting substantially more winners - 27 to nine in the match - but also more errors.
However, she took her chance when it came in the 12th game to win the opening set and then broke serve twice more in the second.
Konta saved both the break points she faced and was relieved to come through after admitting she did not play her best tennis.
She said: "It was very tough out there. I don't think either of us felt quite comfortable, we were both trying to find our feet.
"First rounds are never easy and I'm really pleased to have competed through. So far in the season I feel like I'm building in every match I'm playing."
In the second round, Konta will face Czech Katerina Siniakova, who knocked out then world number one Naomi Osaka at the French Open.
Dart on target in round one
Elsewhere, Harriet Dart used her royal support to good effect to record her first ever victory at Wimbledon.
The Duchess of Cambridge made a rare visit to one of the All England Club's outside courts to watch British number four Dart take on American lucky loser Christina McHale.
Sat between British player Katie Boulter, who is missing the tournament through injury, and Fed Cup captain Anne Keothavong, the Duchess cheered on Dart, although she had left by the time the 22-year-old battled to a 4-6 6-4 6-4 victory after two hours and 19 minutes.
Dart, ranked 182, pushed Karolina Pliskova to three sets on her Wimbledon debut last year and had chances in the first set before being broken in the final game.
Holding serve proved tough for both women, particularly in the third set, but Dart broke a run of seven straight breaks to clinch victory and a second-round clash with either former champion Garbine Muguruza or Beatriz Haddad Maia.
