Who We Are...

FuzzyYellowBalls.com (FYB) was founded in 2007 by two friends from first grade: Will Hamilton and Adam Sieminski.

As kids they built LEGOs, and as 20-somethings they decided to start a website in Will’s parents’ basement to help league and club players win more matches, have more fun, and consistently improve their games.

Will brought the tennis chops and Adam brought the technical wizardry.  Although it’s common now, FYB was the first website to upload instructional videos to Youtube, which have amassed about 60 million views to date.

Today, FYB has graduated from Will’s parents’ basement and now partners with the best players and coaches of all time, like Martina Navratilova and the Bryan Brothers, to distill down their expertise and bring it to you in a way that will help you improve, whether you’re just starting out or have an NTRP rating and compete in leagues and tournaments.


"I absolutely love this. I was a losing doubles player at all levels. Nobody wanted to be my partner. After taking these courses, I started working on my game, I did a bunch of the drills and I worked on using plays with my partners. Now, I was undefeated in USTA 3.5 until a few weeks ago, and I am winning more frequently at the 4.0 level as well. Learning from the best ever is a no-brainer."

Dan Schank
4.0 Player

"I have loved taking part in the Windshield Wiper Forehand program, and seeing the massive impact it has made on my forehand. After starting the program, I realized that I wasn't gathering enough power from my core, and that I had a ton of room for improvement. It's been remarkable to see how much more power and spin is available in the shot than what I had previously thought I was capable of."

Anita Joyce
4.0 Player from Texas

"When you get over 29 (or 39) you have only so many hours of court time that your body can handle. The Fuzzy Yellow Balls courses have been a huge value for me because I can put 15 minutes of video time in a day to supplement my on-court time and improve my mental game. Will and the pros have helped me go from beginner four years ago, to playing on the top club team in a 4.0 - 4.5 doubles league."

Jay Berkowitz
4.5 Player

"Fuzzy Yellow Balls' lessons on match strategy have elevataed my game. They helped me move from a mostly defensive baseliner to a player with a plan who's trying to be offensive at the right times. Their lesson style makes you think when you are on the court, and always be one step ahead of your opponent."

Maureen R
3.0 Player from The UK

"The fact that Fuzzy Yellow Balls' reputation has now stretched across the globe is no surprise to me. They seemed to have developed an approach that I'm convinced is unique among tennis professionals. Whether you are a novice or a ranked club player, they will have you thinking and responding differently on court within minutes. They use a highly cognitive-tactical approach, a refreshing change from the technique-saturated emphasis of most others out there."

Robert Partington
3.5 Player from Massachussets

"Fuzzy yellow balls has opened my mind to new techniques and strategies that I’ve never thought of before! My decision making was never a strong suit - especially in doubles, but now with these programs it has made me see all of the possibilities with placement and strokes for different situations in matches. I am winning more matches than ever! I’m so happy I found University and would recommend it to anyone!"

Christina Shifflett
3.5 Player

"Serve and volleyer and longtime fan and customer of FYB here (who has bought I think all of your courses — including the Singles Playbook when you first released it some years ago). Your mini-Playbook on Beating the Pusher was great — easily the best out there, and everything you said to do has worked; my game typically beats pushers and lobbers routinely, but it hasn’t necessarily been easy. But your mini-playbook on the pusher has me now BAGELING pushers. Out of the programs offered by you and your competition, yours is the best one against this player type, and that’s what I’ve told all of my friends!"

Tony C.
California

"I absolutely love Fuzzy Yellow Balls. I am a self-taught tennis player for the past 12 years and am now playing at the 4.5 level. I have learned so much from FYB about the correct position I need to be on the court, and the correct shot I need to attempt based on that."

Sandra Mason
4.5 Player from Virginia

"Will Hamilton is a genius at finding the small change needed to make a big difference in my game. In particular, the footwork programs have been incredibly helpful. Turns out that if you're in position to hit your shot, it's a lot more likely to be a good shot! My forehand and backhand have both improved as a result, and now I'm working to take advantage of my strong forehand by moving in and ending points at the net."

Dan Ruben
4.0 Player from New Jersey
