A three-year member of the CSI Dolphins soccer team and a two-year captain, Diaz was a transfer to the Dolphins as a player and a three-time CUNYAC All-Star, including a Defender of the Year CUNYAC award winner in 2015. He will now transition to the coaching circle, hoping to work with CSI's back line to provide stability and poise.
Diaz finished his career for the Dolphins with four career goals, including a game-winner.
