NEW YORK — Britain's Johanna Konta continued to enjoy her time in the sun and the U.S. Open spotlight as she stopped 18th seed Andrea Petkovic 7-6(2) 6-3 on Saturday to reach the fourth round of a grand slam for the first time.
It was the second upset in as many matches for the 24-year-old qualifier who toiled for three hours and 23 minutes in searing heat on Thursday to dispatch eighth seeded Spaniard Garbine Muguruza in the longest U.S. Open women's match since the introduction of the tiebreak in 1970.
The sun returned to Flushing Meadows on Saturday but again it was Konta's opponent feeling the heat, with Petkovic calling a medical timeout after going down a set and 3-0 in the second.
