Strength and conditioning trainer Scott Byrnes has left Ana Ivanovic’s team, just five months after he left Victoria Azarenka to reunite with the Serbian, TENNIS.com has learned.

The Australian worked with Ivanovic between July 2006 and July 2009, when she won her sole Grand Slam at the 2008 French Open.

Ivanovic parted ways with her ftiness trainer and childhood friend, Marija Lojanica, in March; during Wimbledon, she announced that she had hired Nigel Sears to be her coach, who stepped down as the head of women’s coaching for the Britain’s Lawn Tennis Association.

Ivanovic is currently in Australia with her boyfriend, golfer Adam Scott. It is unclear at this time whether she will hire a new trainer.—Matt Cronin
