CoCo Vandeweghe has stopped working with Craig Kardon and will be coached by Pat Cash, according to Melbourne’s *Herald Sun*.
"I’m excited, as I believe she has the potential to win a Slam,” Cash said. “She has the power to wipe players off the court. We will be aiming to use that skill through the grass-court season and onwards."
Vandeweghe, who reached the semifinals of the Australian Open, did not win back-to-back matches on the WTA tour again until Madrid, and fell in the first round at the French Open.
