Legendary Australian tennis player and coach Peter McNamara, a fixture in the stands on the WTA tour in recent years, passed away over the weekend after a courageous battle with prostate cancer. 

McNamara, a former Top 10 player on the ATP tour in singles and doubles, won three Grand Slam doubles titles in his career in the late 1970s and early 1980s, and turned his eye towards coaching after retiring as a player.

On the WTA, McNamara most recently coached China's Wang Qiang, helping her break into the Top 20 of the WTA rankings last year after working together since 2015. 

The pair parted ways earlier this year.

"I would like to show gratitude towards Qiang Wang, and her entire team around her, for these exciting and joyful four years together that created an amazing journey," McNamara said in February's statement. 

"Qiang has taught me patience and understanding, at the same time as I have lived a dream that she made possible. I would like to thank her for all and wish her all the best in the future."

Wang later told WTA Insider at the BNP Paribas Open in Indian Wells that the pair's collaboration ended because the Aussie was unable to travel full-time due to his health.

As news of his passing circulated around the tennis community on Sunday, WTA players past and present took to social media to share their thoughts on the one fondly called 'Macca.'

McNamara is survived by his wife, Petra, and four children, Rochelle, Julian, Justin, and Daniel.
