MELBOURNE, Australia — After three previous losses in Australian Open quarterfinals, Jessica Pegula defeated Amanda Anisimova 6-2, 7-6 (1) on Wednesday to advance to the final four at Melbourne Park for the first time.
It marked Pegula's 14th win in her past 15 matches against fellow Americans, continuing her strong run of domestic dominance.
In the earlier quarterfinal at Rod Laver Arena, Elena Rybakina defeated Iga Swiatek 7-5, 6-1 to prevent the Polish player from completing a career Grand Slam of singles titles.
Pegula meets Rybakina in one semifinal on Thursday, while top-ranked Aryna Sabalenka will play Elina Svitolina in the other.
The 31-year-old Pegula also beat Madison Keys, another American and the defending champion, in her previous match to advance to the quarterfinals.
Pegula is looking for her first Grand Slam title while Rybakina is after her second after winning Wimbledon in 2022.
Pegula was almost perfect in winning the first set and closed it out with an ace. The second set was much closer with each breaking the other twice.
''I've been waiting for the time when I can kind of break through,'' she said of her semifinal appearance. ''I feel like I really play some good tennis here and I like the conditions.''
