Emma Raducanu working with 4th coach in just 13 months in effort to turn around poor season

• Emma Raducanu is working with her fourth coach in just over a year.
• The British teenager has split with three coaches since making her Grand Slam debut at Wimbledon last year.

Emma Raducanu is working with her fourth coach in just over a year as she looks to turn around what has been a difficult first full season on the WTA Tour.

According to MailOnline, the 19-year-old has recently tapped Russian coach Dmitry Tursunov, who will be at her side when she competes in the Citi Open in Washington, DC next week.

If their initial spell together goes well, Tursunov will then remain as Raducanu's coach for the US Open and the rest of the coming North American swing, reports MailOnline.

Tursunov has most recently worked with Estonian player Anett Kontaveit, helping her reach the WTA Top 5, and has also previously coached World No. 6 Aryna Sabalenka of Belarus.

As a player, Tursunov won seven titles on the ATP Tour and helped Russia win the Davis Cup in 2006.

Raducanu has split with three coaches since making her Grand Slam main-draw debut at Wimbledon last year.

After making it to the fourth round at the All England Club, she parted ways with Nigel Sears and joined up with Andrew Richardson, who went on to guide her to a stunning victory at the US Open.

Despite the victory at Flushing Meadows, however, Richardson's contract was not extended, and Raducanu instead appointed Torben Beltz in November.

The British teenager then split from Beltz in April this year and has since been without a coach.

Shortly after her split from Beltz, Raducanu opened up about her decision to keep rotating her coaches, telling the Wall Street Journal Magazine: "It might not work for anyone else, and people might look at me like I'm crazy, but I trust my own decision-making."

Since winning last year's US Open, Raducanu has struggled with form and a variety of injuries that have seen her withdraw from several tour-level competitions.

In February, she pulled out of the Guadalajara Open with a hip injury before doing the same at May's Italian Open, due to a back strain.

In June, she withdrew from both the Birmingham Classic and Eastbourne International after being hurt at the Nottingham Open.

She was declared fit to play at Wimbledon, however was knocked out in only the second round by France's Caroline Garcia.
