Cape Town - Belgian Elise Mertens extended her winning streak to 12 matches by beating Australian Ajla Tomljanovic 6-2, 7-6 (7/4) in the final of the Rabat Grand Prix in Morocco on Saturday.
The 22-year-old Mertens led by a set and 5-3 before her 24-year-old opponent fought back to force a tie-break.
The Belgian however maintained her composure to comfortably seal her third title of the year after winning the Hobart and Lugano tournaments.
Tomljanovic's cause was undone as she racked up 46 unforced errors in an effort to find the lines against the in-form Mertens.
