Karolina Pliskova revealed she and coach Sascha Bajin had parted ways on Monday after an 18-month partnership.

“One of the best coaches out there, good luck my friend,” tweeted the former world No. 1.

Pliskova added Bajin, who served as a longtime hitting partner to Serena Williams in addition to coaching the likes of Naomi Osaka, Dayana Yastremska, and Kristina Mladenovic, to her team ahead of the 2021 season.


Though the collaboration yielded no titles, Pliskova nonetheless enjoyed her best major result in nearly five years when she reached her first Grand Slam final since the 2016 US Open at last year’s Wimbledon Championships.

Following a narrow defeat to top seed Ashleigh Barty, she qualified for a fifth consecutive WTA Finals, where she exited in the round robin stage.

The 2022 season has been far less successful for the perennial Ace Queen, who currently trails reigning Wimbledon champion Elena Rybakina. An off-season hand injury kept her from playing the Australian Open and has since returning to action in Indian Wells, she has only won back-to-back matches at two tournaments out of 11.

At Wimbledon, she lost in the second round to home favorite Katie Boulter in three sets.

“Even good things sometimes come to an end,” Pliskova wrote. “I would like to thank @BigSascha for everything he did for me and my team.”

Pliskova, who turned 30 in March, is yet to announce a new head coach.
