British number two Cameron Norrie beat American Stefan Kozlov in straight sets to reach the second round of the Mexican Open.
Norrie won 6-3 6-3 against the 23-year-old qualifier to set up a meeting with Italian Fabio Fognini.
Their only previous meeting ended in defeat for the 25-year-old Briton in Los Cabos, also in Mexico, in 2018.
Fellow Briton Jamie Murray reached the men’s doubles quarter-final with Brazilian partner Bruno Soares.
The pair are still on course for their third Acapulco title after beating India’s Rohan Bopanna and Pakistan’s Aisam-Ul-Haq Qureshi 6-7 (4-7) 6-2 10-1.
They will face British brothers Ken and Neal Skupski in the next round.
Dart beaten in Monterrey Open
Britain’s Harriet Dart lost 6-4 6-3 to Slovakia’s Viktoria Kuzmova in the second round of the women’s Monterrey Open.
Dart, 24, ranked 153rd in the world, had eliminated fellow Briton Heather Watson in the first round but could not repeat the feat against 22-year-old Kuzmova, the world number 104.
Kuzmova gained the crucial break of serve in the 10th game to take the first set, although Dart immediately broke back at the start of the second set.
However, Kuzmova then won four games in a row on her way to clinching the win.
She will meet either Slovakia’s Kristina Kucova or Canada’s Leylah Fernandez in the quarter-final.
