Two Grand Slam champions have changed agencies, with Dominic Thiem becoming the first client of Kosmos and Bianca Andreescu signing with IMG.

Thiem had been represented by Vienna tournament director Herwig Straka since he splitting in 2019 with coach and agent Gunther Bresnik, with whom he reached a settlement a few months ago. Straka has said their arrangement was an interim one until Thiem found new representation.

It also represents the entry of Kosmos into player representation—the company started by soccer player Gerard Pique got involved in tennis when it poured millions into a Davis Cup revamp with the ITF.

Thiem will be repped by Galo Blanco, a former coach, saying, "I am very happy that Galo is part of the team again."

The 27-year-old from Austria, who won the 2020 US Open, is No.4 in the rankings.

Andreescu, who had been represented by Octagon since the start of her professional career, is now with IMG. The 21-year-old Canadian won the 2019 US Open, and has made some other recent changes to her team.

She split with her coach Sylvain Bruneau following a first-round exit at Roland Garros, also getting a new trainer this season as she attempts to return from a series of injuries.

Andreescu is ranked No. 7 and played this week in Berlin. Thiem is next competing at Mallorca.
