Serena Williams recovered from dropping the opening set to show glimpses she is getting back to her best against Kaja Juvan at Wimbledon.
The seven-time winner, who has been injured for much of this year, found her range at the start of the second set and went on to beat the 18-year-old Slovenian 2-6 6-2 6-4.
"I just have to remember that I'm best at closing matches, I'm good at it," Williams said.
"I just have to keep the mind frame of where am I, what do I do mentally to close matches. I have to kind of just shut my eyes and get there.
"Like I keep saying, it's just experience and match play. In the past two years I haven't played a lot of matches. I'm just trying to kind of get that back."
After an error-strewn first set Williams, in front of the watching Duchess of Sussex, rediscovered her consistency and in doing so forced more mistakes from her young opponent.
A break in the first game settled the American, and a second break brought the match level.
The 23-time grand-slam winner, who has a doubles date with Andy Murray on Friday, was by now in the ascendancy.
Juvan, ranked 133 in the world, bravely clung on in the decider but a solitary break saw Williams safely through.
"It was definitely coming together as the match went on. I'm just low on matches basically. I could feel it," she added.
"But I'm getting there. I just have to take every match as five matches, really learn from every single point."
