Coco Gauff was twice a point away from being pushed to a third set by Emma Raducanu at the Australian Open but steadied herself and went on to a 6-3, 7-6 (4) victory on Wednesday in the first head-to-head meeting between two young stars of tennis. (More Tennis News)
"This was a long-anticipated matchup," said the seventh-seeded Gauff, who was the runner-up to No. 1 Iga Swiatek at the French Open last June. "Basically since the draw came out."
The 18-year-old from Florida moved into the third round at Melbourne Park for the first time since 2020. She is the youngest seed in the women's field.
Raducanu, a 20-year-old who represents Britain, has not made it past the second round of a Grand Slam tournament since she won the 2021 U.S. Open as a teenager. That made her the first qualifier to claim a major trophy.
Currently ranked 77th, Raducanu has been dealing with an ankle injury. Yet she was so close to extending this match, holding a pair of set points while ahead 5-4 in the second set.
On the first chance, Raducanu sailed a backhand long. On the second, she dumped an attempted drop shot into the net.
That helped Gauff hold serve there. More miscues by Raducanu tilted the tiebreaker -- and the match -- Gauff's way.
"I just told myself," Gauff said, "to hang in there."
