Jil Teichmann needed seven match points to reach the first hard-court semifinal of her career with a 6-2, 6-4 victory over CiCi Bellis at the Top Seed Open on Friday.
Teichmann's next opponent will be either 23-time Grand Slam champion Serena Williams or Shelby Rogers. The start of their match was delayed by rain Friday.
This hard-court tune up ahead of the U.S. Open — which starts Aug. 31 in New York — is the first tennis tournament in the United States since the start of the coronavirus pandemic.
Teichmann served for the victory at 5-3 in the second set and was one point from winning a half-dozen times in that game, but couldn't convert, and Bellis eventually broke on her fourth chance.
In the next game, though, Teichmann got a seventh opportunity to end things and Bellis put a forehand into the net.
"That," Teichmann said, "was tough mentally."
The quarterfinals on the other side of the draw are 16-year-old Coco Gauff vs. No. 8 seed Ons Jabeur, and Jennifer Brady vs. Marie Bouzkova.
Serena Williams Thursday dismissed her sister, Venus 3-6, 6-3, 6-4.
At Friday game against Shelby Rogers Serena bowed in the quarterfinal 6-1, 4-6, 6-7.
