Linz - American teenage sensation Coco Gauff reached the first WTA final of her career on Saturday as the 15-year-old beat Andrea Petkovic 6-4, 6-4 in the last four in Linz.
The current world number 110 is set to climb to at least 80th in the rankings next week.
Gauff showed plenty of variety in her game as she beat the 75th-ranked Petkovic, relying frequently on well-executed drop shots.
The youngest-ever winner of a WTA Tour title was two-time US Open champion Tracy Austin, aged just 14, at Portland in 1977.
Her mother arrived in time to watch her daughter, flying in from Luxembourg after arriving from Florida.
