The 31-year-old officiated in the final of the World Cricket League Division 2 between hosts Namibia and Oman.
Australia's Claire Polosak said it was a "special day" as she made history in becoming the first female umpire to stand in a men's one-day international.
The 31-year-old officiated in the final of the World Cricket League Division 2 between hosts Namibia and Oman at the weekend and admitted she would "sleep well" after her performance.
"It was a special day for everyone and I wanted to do the best I can.
"There was a little bit of intensity out there, some argy-bargy between the teams but I nipped it in the bud with a quiet word.
"Everyone responded well, there were no issues with player behaviour."
Polosak has already stood in 15 women's ODIs, the first one in November 2016 between Australia and South Africa.
She has also umpired the semi-final of the Women's T20 World Cup in 2018 between England and India and four matches at the 2017 Women's World Cup.
Polosak was the first woman to stand in a men's domestic fixture in Australia in her first List A match in Australia in 2017.
"I had a couple of big calls," she added of Saturday's game which was won by Namibia by 145 runs.
"Big caught behinds, lbws which I was pleased with. You never walk off completely happy but I will sleep well tonight."
Polosak has already blazed a trail -- she was the first woman to stand in a men's domestic fixture in Australia in her first List A match in Australia in 2017.
In December last year, she and her South Australian counterpart Eloise Sheridan became the first female umpires to officiate on-field together during a professional match in Australia when the Adelaide Strikers hosted the Melbourne Stars in the WBBL.
Sri Lanka started the tournament as rank outsiders and finished sixth of the nine teams, registering one of their three wins against the world's top-ranked one-day international side and hosts England.
It was a superb display by the underdog Black Caps, who came into the match on the back of three straight defeats by Pakistan, Australia and England and only qualified for the semi-finals on net run-rate, while India topped the 10-team group stage.
Reigning champions Australia made one change after a surprise 10-run defeat by South Africa at Old Trafford, with the recently called-up Peter Handscomb replacing injured batsman Usman Khawaja.
In a match pitting two of the bottom-placed IPL 2019 teams — Rajasthan Royals (RR) and Royal Challengers Bangalore (RCB) — against each other, it was the Royals who finally opened their account this season with an 7-wicket romp at the Sawai Mansingh Stadium in Jaipur on Tuesday. RCB meanwhile remain rooted to the cellar -- still pointless -- by virtue of this loss.
