They worked together for four years in the past. During that time, Halep won the 2018 French Open for her first Grand Slam title and twice finished at No. 1 in the WTA year-end rankings. She also was the runner-up at three major tournaments.
In November 2018, Cahill said he was taking a 12-month break from coaching to spend more time with his family and do TV broadcasting. Without him as her coach, Halep won Wimbledon this July. She is currently ranked No. 6 after a second-round loss to Taylor Townsend at the U.S. Open.
