Eugenie Bouchard needs a new coach for the second time this year.

Her agent, Jill Smoller of WME/IMG management, confirmed to TSN's Mark Masters that the split between Bouchard with Sam Sumyk happened after just six months.

Bouchard went 4-13 while working with the Frenchman, who had previously coach Victoria Azarenka.

The 21-year-old from Westmount, Quebec let go longtime coach Nick Saviano last November after a breakthrough season which saw her make the Wimbledon final as well as the semifinals of the Australian Open and French Open. She reached the top five in the WTA World Rankings.

Sumyk was hired in February 2015 and Bouchard's play has plummeted drastically ever since. She has fallen to 25th in the world rankings and is 8-14 on the season, including first round exits at the French Open and Wimbledon. 

Bouchard is in Toronto for the Rogers Cup, where qualifying starts Saturday. She will be working with Serbian Marko Dragic for that event, and there is no word if he will be the new permanent replacement as coach.
