Sloane Stephens splits with coach Sven Groeneveld just before US Open

Just a week before the US Open, former champion Sloane Stephens has parted ways with coach Sven Groeneveld. The 2017 titlist took to Twitter on Monday to announce that she will no longer be working with the Dutchman.

Since kicking off her summer hard-court campaign, Stephens has won just one match in three tournaments, falling in her Washington and Toronto openers. In Cincinnati, she needed three sets to defeat Yulia Putintseva before losing to eventual finalist Svetlana Kuznetsova.

Having played without a coach for the first five months of the season after splitting with Kamau Murray, the 26-year-old American joined forces with Groeneveld in May. Under Murray’s guidance, Stephens won the US Open in 2017, the 2018 Miami Open and reached the French Open final a couple of months later.

Groeneveld has worked with Grand Slam champions including Monica Seles, Maria Sharapova and Ana Ivanovic.

Stephens has yet to announce her new coach.
