Teenage sensation Coco Gauff will face Jelena Ostapenko in her first WTA Tour singles final after beating Andrea Petkovic in straight sets at the Linz Open.
Gauff needed a lucky loser spot to take her place in the main draw after failing to qualify but could claim the title on Sunday following a 6-4 6-4 defeat of Petkovic.
The 15-year-old American saved nine of 10 break points she faced and rallied from 2-0 down to win the first set before claiming the only break of the second to oust German Petkovic on Saturday.
Gauff showed great defense and mixed up her game impressively, making Petkovic pay for a double fault which gave the teenager a 3-2 advantage in the second set.
The Florida native, set to move into the top 100 in the rankings on Monday, won 71 percent of points on her second serve and broke new ground when she put away a textbook volley.
