We first met Kimberly when she was identified #3 on our "Biggest Amateur Movers" list from July. Biggest movers are folks that have shown the largest change in their DUPR rating in a given amount of time.


This is an impressive accomplishment on it's own, but we were floored when she reached out to share her story of incredible resilience and perseverance.


Read Kimberly's Story In Her Words:


"I’m such a social media introvert and I rarely post anything but today is a pretty special day for me and I wanted to share it. Today I had my very last physical therapy session after going twice a week for the last 7 years.

In August of 2015 I had my first Open Hip Dislocation/Femoral Derotation surgery in which my hip sockets were reformed and my femurs were cut in half and rotated 20 degrees. We did one hip at a time, the second hip was 15 months later. The surgeries were very long and my spinal cord became pinched during the second hip surgery because of the way I was positioned. This complication greatly delayed my healing and it wasn’t until 18 months later that I had another surgery to decompress my spinal cord. I spent many, many months in a hospital bed in our home, and many years dependent on a wheelchair, walkers, and crutches to get around. I had to use those little motorized carts to shop once I could leave the house. With the change in the position of my femurs along with the spinal cord complication, I had to learn to walk all over again. I looked like Woody in Toy Story with my joints zig zagging in different directions. I couldn’t get my feet to line up with my knees and my knees to line up with my hips. My body had been rearranged and my brain couldn’t figure out how to walk again.

It’s been a very slow and very painful journey. Anyone who knows Dan and me, knows that we like to be active. Hiking, tennis, scuba diving, cycling, you name it…we just love to play. It was a tremendous loss for us to be confined to the house and not know if I would ever walk again, much less get to be active and play again. I was DETERMINED to get back to normal (active lifestyle) and it was so frustrating that my body wouldn’t work anymore. At one point, a couple of years ago, one of my PT’s gently suggested that I try different hobbies that I could do, instead of focusing on what I could no longer do. She suggested that I should just ‘go live my life’ with the limitations I had. Boy, that fired me up big time. I said OMG are you saying I need to take up something like cooking or sewing? I’m sure Dan would love if I was a better cook but seriously kill me now! Okay I’m wrapping it up I promise. A couple of years ago, I was still using a walker for anything outside the house and Jim and Sonya Phillips introduced us to Pickleball. Obviously, I was there just to watch. It looked so fun! Everything in me wanted to be out there playing, so I convinced Dan to let me come out on the court with him. I stayed in one spot and if the ball came right to me, I hit it! Oh my goodness! The spark of life that flooded my soul in that moment…I can’t even describe it. I was still so disabled at that point that if I even transferred my weight on my right hip it was screaming pain…but hey…I was out there and I was feeling alive. Pickleball motivated me to work even harder in PT. We would go out to play and I would just get the balls that came to me. Little by little I could move around the court more…Now…on this my last day of PT…I’m out playing Pickleball against people who have no idea what I’ve been through and I’m beating them   Dan and I have been traveling around competing and winning medals together. We feel 20 years younger.I want to thank God for carrying us through those long, painful years, and for healing my body bit by bit. He has been so very good to us. And Dan is my hero, my knight in shining armor. I wouldn’t have made it through this without him! We did it my love! Let’s see…7 surgeries, in 7 years! I’m estimating 88 trips to Stanford, 18 nights in the hospital, $2.89 million in medical bills, and last but not least 498 hours sitting in Bay Area traffic! "


Amazing work Kimberly! Truly an inspiration to us all.

Saving the World, One Pickleball at a Time

"We're not just about playing; we're about fostering a thriving pickleball culture."

Orlando Advanced Pickleball (OAP) started as a small community of pickleballers, to now having cultivated a huge group of pickleball enthusiasts in Florida, boasting over 3,900 members. OAP, founded in April 2023, joined DUPR in October, is not only encouraging level base play, but also about making a positive impact on the environment.

Beyond the court, OAP is committed to sustainability through their pioneering pickleball recycling program in Florida. By converting worn-out pickleballs into functional zip ties, OAP has diverted over 225 lbs of pickleballs from landfills, equating to over 1,500 pickleballs recycled and counting. "We're not just about playing; we're about fostering a thriving pickleball culture", says Dave John, founder of OAP. Strategic bins have been placed across key locations in Central Florida, with plans for expansion pending local government approval. In the meantime, individuals are encouraged to transport their worn-out balls to courts equipped with recycling bins to help preserve the environment and support OAP's mission to ensure pickleballs don't end up in landfills, both for the sake of environmental responsibility and for the legacy future generations of pickleball enthusiasts.

“We're committed to ensuring pickleball don't end up in landfills, both for the sake of environmental responsibility and for the legacy we leave for future generations of pickleball enthusiasts,” Dave adds. The organization is also hosting a Fundraising Tournament in June, to raise money for the Second Harvest Food Bank of Central Florida, that already has over 220 registrants!

Founded just a year ago, OAP wasted no time in partnering with DUPR shortly after its inception. “Recognizing that DUPR is the pinnacle of accuracy and consistency in pickleball rating systems, OAP swiftly joined forces. Now, OAP is preparing for upcoming events, ensuring that scores are entered into DUPR”, Dave confirms. 

The OAP Team recognized the importance of recycling pickleballs after noticing many damaged balls being thrown away in trash cans at courts. Standard recycling facilities cannot process thermoplastic molded resin, the material pickleballs are made from, so OAP took the initiative to ensure these balls do not end up in landfills. 

“Every contribution helps our collective efforts” David adds. “We can help save the world, one pickleball at a time." Whether it is through league participation, tournament play, merchandise purchases, lessons, or donations, all of it helps towards the goal of a more environmentally efficient pickleball community.

OAP operates their recycling initiative without any financial gain, emphasizing their dedication to making a difference in the environment and the pickleball community. As a relatively new organization, OAP has quickly established itself in the pickleball world through partnerships with organizations like DUPR for accurate rating systems and innovative initiatives like pickleball recycling.

The Power of Sibling Partnerships in Pickleball

On April 3rd, at the Major League Pickleball Premier Level Draft, the New York Hustlers selected Jackie Kawamoto with the 16th pick of the 2024 draft.

Shortly after, the Los Angeles Mad Dogs used the 26th pick to select Jackie’s twin sister, Jade Kawamoto.

The final rosters for the MLP Premier teams are comprised of the 48 most in-demand players in professional pickleball. Six of those coveted spots went to three pairs of siblings: the Kawamoto sisters, Ben and Collin Johns, and Jorja and JW Johnson.

Whether as practice partners, doubles teammates, or competitors, sibling teams have a unique chemistry that is difficult to replicate. Their shared history, communication skills, trust, competitive edge, and motivation all contribute to their success on the court.

For Jackie and Jade, the sibling advantage has helped them rise rapidly through the ranks of professional pickleball.

“Just having that person to always practice with was definitely an advantage for us,” says Jackie. “I'm a righty and Jade is a lefty, and we move together very well. I think that's our biggest strength. I know where I need to be when she gets pulled wide, and vice versa. I know all of her shots. We just know each other's game so well.”


“We've practiced with each other our whole lives, so it comes naturally,” adds Jade.

Like many professional pickleball players, the Kawamoto sisters have a background in competitive tennis, playing throughout their childhood and into college. 

Their journey with pickleball began in 2019.

“At first it was just fun, something to do with the family,” says Jade. 


“It didn't take long for all of us to get hooked and pretty much play nonstop,” adds Jackie.

They started competing in 2021, and in less than 3 years, they’ve become top rated pros. The Dink recently rated Jackie and Jade the number five women’s doubles team in the world for 2024, and their 5.9+ DUPR ratings demonstrate how far they’ve progressed in their short time since finding the sport.

“Chemistry is such an important part of this game because of the nature of the game and how quickly it goes,” Jackie explains.

Jade adds that the emotional support is just as important as the training.

“When you grow up with each other, and you're the same age and have gone through similar experiences… I know it's a cliche or whatever, but it does help you on the court to have someone that knows your emotions and knows how to bring you up when you're down,” she says.


This season, that bond faces a new challenge. Where the Kawamoto sisters played together for the ATX Pickleballers in 2023, this year they’ll meet as rivals.

It’s fitting, perhaps, that their new teams represent the sister-cities of New York and Los Angeles, two American metropolises that share similarities and a healthy rivalry.

For Jade and Jackie, meeting head-to-head is an opportunity to keep improving their game.

“We were pretty competitive with each other when we were younger,” Jackie recalls. “It always pushed us to be a little bit better.”

“We still like to be competitive with each other,” Jade says, “but mostly in a fun-spirited way, not like ‘I have to be better than you at this’. It helps us get better if we're trying to have that competitive mindset, but also keeps it fun.”

How the AI Boom Is Making Pickleball a Success

AI’s Pickleball Potential

Sports aren’t typically the first thing that comes to mind when you think about the Artificial Intelligence (AI) revolution. However, AI in sports is now synonymous with big business. Estimates value the sports AI market at more than $2 billion, and research suggests that it may reach more than $7 billion by 2027. Currently, AI is being used for everything from training NFL players to shaving time off their 40-yard dash to predicting and preventing injuries on the basketball court. And it’s poised to have a significant impact on the sport of pickleball.

Harnessing the Power of AI for Pickleball

AI systems use mathematical algorithms that generate highly accurate analysis in real time. For pickleball, data can be collected via wearable sensors and high-definition motion capture cameras to record players' footwork, paddle angles, and shot choices. This data can be transformed into a format processed by an algorithm and can be used to train the AI model, allowing it to learn patterns and relationships. The model is then integrated into an application or program and is the basis for making predictions on new data that is collected. The more data it acquires, the more the algorithm adapts and the better its ability to simulate human intelligent processes. Coaches can then reference the data and immediately adjust a player’s mechanics and techniques, repeat the drill or session, and compare results.

But AI isn’t just for pickleball pros. Recreational players are already enjoying the benefits of AI. Training tools like SwingVision and PB Vision bring the power of AI to local courts without the need for high-end equipment or professional-grade video. By uploading footage shot on a smartphone, these systems can analyze player movements, pinpoint problems in swing speed and follow through, and provide suggestions for improvement. In addition, AI is becoming an integral part of emerging pickleball virtual reality (VR) simulations that produce engaging immersive, customized training programs.

In addition, the recent partnership between leading global pickleball rating system DUPR and sport and AI analytics technology pioneers Playsight has opened up new possibilities. PlaySight’s AI automated highlights also allow players to relive their best moments in a match instantly. The collaboration promises to redefine how players experience and interact with the sport.

Preventing Injury and Speeding Recovery

Off the court, AI is showing great benefits in improving player health and conditioning. Systems can evaluate heart rate and joint stress and alert players to potential injury. Next-generation pulse oximeters incorporate AI into handheld devices that measure respiratory rate, temperature, and blood saturation levels. 

AI can also help accelerate recovery times from injuries. Trainers and physical therapists are increasingly relying on AI-generated results to create personalized rehab programs to get players back on the court faster and prevent re-injury.

In addition, manufacturers of pickleball equipment, especially paddle companies, are using AI-powered systems to determine material specifications and performance metrics for the design of their newest products. Because of its ability to perform analysis on a microscopic level, AI can identify the optimal materials for improved power, control, and durability and give manufacturers next-level customization options to develop paddles suited for a variety of playing styles. These advancements are poised to propel paddle sales, which are projected to reach $253.8 million by 2028 and are currently more than $125 million in the US alone.

It's an exciting time for pickleball and AI will continue to play an ever-expanding role in the sport’s future. As more players tap into AI’s ability to achieve better results on the court, it’s likely there’ll be a corresponding increase in their DUPR ratings.
