A look at the updated WTA rankings this week:
Elina Svitolina and her new coach got off to a shaky start when she fell in her opening round in Wuhan to Aryna Sabalenka, but she is remaining positive.
Svitolina is newly working with Nick Saviano, who owns an academy and has previously coached Sloane Stephens and Eugenie Bouchard. Thew world No. 6 chose to make a change following her fourth-round defeat at the US Open.
"I decided to stop, to try something new, to have a different opinion on my game because I think I need fresh look," she told press before the tournament. "I think Nick is that kind of person that can bring the experience."
The 24-year-old had been coached by Thierry Ascione, who also works with Jo-Wilfried Tsonga. Svitolina has had half a dozen coaches since 2015, including a consulting arrangement with Justine Henin in 2016.
The Ukrainian put together a bigger team to start the 2018 season, including a physiotherapist, but she also dropped a lot of weight, saying it has helped her game. Though she has won three titles this year (in Brisbane, Dubai and Rome), she has not been beyond the semifinals of an event in the second half of the season.
Svitolina joked that she would not be revamping her game completely.
"I don't say the things didn't work because I'm still a Top-10 player. I won big tournaments this year," she said. "I'm always looking for something that can help my game.
"Obviously I'm not going to change massively. I'm not going to hit one-handed backhands straight away."
So far in her career, Svitolina has underperformed at the Grand Slams, having yet to get beyond the quarterfinals. Her next scheduled event is Beijing.
