Meet The Team

Owner & Trainer


Gus Constantino

I started Bottom 9 Sports Academy for the love of the game. As a young player I had big dreams of playing at the Pro level but was told many times it would not be possible. My family and a few great people, however, told me to always go after my dreams. So that's just what I did. After graduating from Oxford High School I went on Scholarship to County College of Morris. After I transferred to Western CT State University to play my last 2 years of College baseball. I then went out to the Arizona Winter League hit .330BA and was given a contract to play in the USPBL in 2016. Went back out to Arizona for the Dessert League of Professional Baseball 2016. In 2017 I was given a new contract to go and play in Kentucky for the Thoroughbred Professional Baseball League. After a strong season I was offered another contract to play for the New Hampshire Wild in the Empire League of Professional Baseball 2018. I was lucky enough to have the opportunity to play in Mexico as well as Puerto Rico. I have been a High School Coach since 2016. I was able to accomplish many things from winning national championships and playing all over the country and many parts of the world, and now looking to aspire and train athletes of all ages, who want to get better and have the B9 team in their corner.
