ADELAIDE - Former French Open champion Barbora Krejcikova made a stuttering start to her 2023 season in the opening round of the Adelaide International 2 on Tuesday, shaking off the rust in a 6-2 7-6(3) victory over Alison Riske-Amritraj.

The 27-year-old Czech, a quarter-finalist at the Australian Open last year, was one of the form players on the WTA Tour in the latter end of last season after she returned from an elbow injury.

The former world number two was clearly not at her very best against the American lucky loser and needed a tiebreak to finally finish off her opponent after being broken when serving for the match.

The 2017 French Open champion Jelena Ostapenko had a less successful day, going down 6-3 6-4 to Russian qualifier Anna Kalinskaya.

Former Australian Open champion was in action at the other warm-up for the year's first Grand Slam and looked in good touch as she beat China's Zhu Lin 6-2 6-2 in the opening round of the Hobart International.

"I felt really good, conditions were a little bit tough but I felt like I played a solid match so I'm super happy," said Kenin, who will play second seed Elise Mertens or qualifier Maryna Zanevska in the next round.
