American Danielle Collins aims for her first Grand Slam final appearance on Thursday morning when she faces Poland's Iga Swiatek in the 2022 Australian Open women's semifinals. Collins, the 27th seed, breezed past Alize Cornet 7-5, 6-1 in Tuesday's quarterfinals, while the seventh-seeded Swiatek needed more than three hours to beat Kaia Kanepi 4-6, 7-6 (2), 6-3. Collins reached this stage in Melbourne in 2019, losing to Petra Kvitova. This also is Swiatek's second semifinal, as she went on to win the French Open in 2020.

First serve is set for 4:45 a.m. ET. Swiatek is listed as the -150 favorite in the latest Collins vs. Swiatek odds from Caesars Sportsbook, while Collins is a +120 underdog.

Danielle Collins vs. Iga Swiatek preview

Swiatek's run to the French Open title gives her the edge in experience. Collins reached this stage once before, but she had not won a Grand Slam match before then and was under little outside pressure. Swiatek should have some confidence from beating Collins in their only previous matchup. She went up 6-2, 3-0 before Collins had to retire with a back injury in a quarterfinal at Adelaide last February. Swiatek went on to win that tournament over Belinda Bencic.   

The 20-year-old Swiatek played a long match Tuesday, but her youth should help her bounce back. Collins has a powerful serve, but the Pole leads this tournament in first-serve return points, which will help neutralize that. Swiatek is 44-16 in matches since the start of 2021, and her energetic style creates a lot of winners and unforced errors. She has battled through this tournament while not at her best, and she should be mentally prepared for another tough test. 

Collins is a fierce competitor with a lot of power, and she is finally healthy and ready to prove she is a top-10 player. The 28-year-old, a two-time NCAA singles champion at the University of Virginia, was diagnosed with endometriosis last year. That led to surgery to remove a tennis-ball sized cyst, and she says she feels like a new person. She has been playing like it, losing just two sets in this tournament. She is 45-15 in her matches since the start of last season.
