After Coco Gauff’s shocking 23-double fault display at Canadian Open, Serena Williams’ ex-coach Rennae Stubbs calls for modifications to her serve

After Coco Gauff’s surprising performance at the Canadian Open — where she racked up a jaw-dropping 23 double faults in a single match — fans and tennis experts alike were left stunned. Among the loudest voices reacting to the unexpected display was Rennae Stubbs, a former coach of Serena Williams and a respected commentator in the tennis world.

Stubbs didn’t hold back. She called attention to a major issue in Gauff’s game that many have been talking about for months: her serve. While Coco is known for her blazing speed, powerful groundstrokes, and fighting spirit, her serve has always been a bit of a weak spot. And this match seemed to expose it more than ever.

The match was hard to watch at times. Despite her talent and athleticism, Gauff’s rhythm on serve just wasn’t there. Each time she tossed the ball, fans held their breath, hoping it wouldn’t result in another double fault. Unfortunately, it did — again and again — 23 times to be exact. That number is almost unheard of at this level of tennis.

Stubbs, reacting to the performance, took to social media to express her frustration. She urged Gauff’s team to seriously address her serving technique and even hinted that it might be time for a coaching change or at least a major adjustment in her training. Coming from someone who once worked closely with Serena Williams — one of the best servers in women’s tennis history — her opinion carries serious weight.

However, fans shouldn’t be too discouraged. Coco Gauff is still incredibly young, just 20 years old, and has already achieved so much — including a Grand Slam title. Struggles like this aren’t unusual for young stars, especially when the spotlight is so bright. What matters most is how she bounces back from it.

Gauff herself has always shown a strong mindset. She’s taken criticism in stride before, and many believe she’ll use this experience as fuel to improve her game. This could be the wake-up call that pushes her to finally fix her serve once and for all.

Everyone’s rooting for her. Tennis is better when Coco is at her best — and no doubt, with the right support and adjustments, she’ll come back stronger.
