TORONTO — Canadian Eugenie Bouchard has parted ways with coach Sam Sumyk, her agency confirmed.

The move comes six months after the Westmount, Que., native hired Sumyk after she had fired long-time coach Nick Saviano in November 2014.

Bouchard has struggled this season and has seen her world ranking slip from No. 7 to No. 26.

Mary Jane Orman of IMG, which represents Bouchard, confirmed the news in an email to The Canadian Press.

An abdominal injury forced the 21-year-old to withdraw from the Citi Open last Friday for a second straight year.

Bouchard is set to compete in the Rogers Cup in Toronto. She plays her first match Tuesday.

A trip to the Wimbledon final last year and semifinal berths at her first three 2014 Grand Slam events put Bouchard solidly on the tennis map, but she hasn’t been able to live up to those expectations, losing 12 of her last 14 matches over WTA Tour and Fed Cup play.
