Coco Gauff has always worn her family ties proudly, keeping close to her parents and siblings even amid a grueling tennis schedule. Her bond with brothers Codey and Cameron has remained unshakable, a constant source of grounding and joy. “It is the best thing in the world for me to be your sibling,” she said last year about Codey, a sentiment that still rings true. Now, as she gears up for the China Open, Coco’s love shines through once again, celebrating her younger brother’s birthday and proving that family remains her greatest victory off the court.

Coco Gauff poured her heart out on social media to celebrate her younger brother Codey’s milestone 18th birthday. The 21-year-old shared a series of heartfelt posts highlighting their unbreakable bond over the years. On Instagram stories, Coco posted a childhood photo of the siblings together with the caption: “happy 18th to my little now not so little brother! I love you @codeygauff,” a sweet nod to the journey from childhood to adulthood.

The celebration didn’t stop there. Coco also shared a playful video of Codey showing off a dance move, tagging him and adding the cheeky remark, “flawda boy.” Codey joined in the festivities, sharing a carousel of images in a post on his account captioned simply, “🔞,” as friends and family flooded the comments with love. Coco kept the energy alive with replies like, “clean w it 😮‍💨” and later, “big man,” capturing the mix of pride and playful teasing that defines their sibling bond.

Even their parents joined the social media cheer. Mom Candi fired up the comments with, “🔥🔥I see you!” while dad Corey couldn’t resist showing off his signature flair, commenting, “👀 at my rolly it’s about that time 🔥🔥🔥🔥.” Later, Candi Gauff, Coco and Codey’s mother, shared a heartfelt Instagram post celebrating her son’s milestone birthday. The post featured multiple photos capturing moments from various family events over the years. 

Some snapshots showed them enjoying theme park adventures, while others depicted the siblings posing together at different locations. Her caption radiated love and pride: “Happy 18th birthday to my favorite oldest sonshine! Today you are an official young adult. You are designed for GREATNESS! Continue to be smart, kind, loving, and athletic. I am your #1 FAN. Always remember you can call and count on your momma. I love you!!! Always and forever, Mom!”

Coco Gauff also maintains a deeply affectionate bond with her younger brother, often sharing glimpses of their connection on social media. Two years ago, she marked Codey’s 16th birthday with a nostalgic trip down memory lane, posting a collage of pictures from their childhood. In her tribute, Coco highlighted her brother’s unwavering support, calling him her “biggest cheerleader.” She captioned her Instagram story, “Happy birthday lil bro. ‘My biggest cheerleader’ – Love you @codeygauff. Enjoy it ❤️❤️,” showcasing a tender mix of gratitude and sibling pride.

The siblings’ relationship is clearly central to Coco’s life, providing grounding amid the pressures of professional tennis. Yet, even as she celebrates family milestones, Coco must refocus on her own game. Her recent loss to Naomi Osaka at the US Open highlighted areas of vulnerability, particularly with her serve, signaling work that cannot be delayed.

Rick Macci foresees a breakthrough in Coco Gauff’s weakness

Rick Macci recently captured attention with his latest insight on Coco Gauff, posting a powerful message on X that has the tennis world buzzing. In his words, “The remainder of the year will give us a small sample size of Coco and the serve. I feel you will see less free presents and a first serve now and then at 125. Watch the Delray Dart flip the double fault script and a new built weapon she will rip.” For Macci, the message is crystal clear: a transformation is coming, and he believes Gauff’s serve is on the verge of evolving from liability to lethal weapon.

Time, however, is not on Coco’s side. Her serve has long been a thorn, a recurring pressure point in high-stakes matches. In Montreal, she double-faulted an astonishing 23 times against Danielle Collins, nearly gifting away an entire set. Her victory in that match spoke volumes about her fighting spirit, but it also underscored the urgent need to address her fundamental weakness.

Ahead of the US Open, Gauff made a bold and decisive move, parting ways with coach Matt Daly and bringing in Gavin MacMillan. Far from a conventional coach, MacMillan is a sports biomechanics specialist, treating technique as pure science and believing that peak performance emerges only when mechanics are perfected. This switch sent a message loud and clear: Gauff is willing to dismantle and rebuild her game if that’s what it takes.

Reflecting on her mindset, Coco told reporters, “Whatever happens for the rest of the year, I just want it to be improvement. I don’t care results-wise. Yeah, last year if you told me I would go win in Beijing and WTA Finals, I would have been, like, whatever, because I didn’t really care going into it. I’m going to probably have that same mindset.”

The stakes rise as the China Open approaches, presenting Coco with a chance to showcase the fruits of her rigorous work. Fans and critics alike will watch intently to see if she can flip the narrative around her serve.
