Space, a standout at DeSoto (Tex.) High, pledged to Leonard Hamilton and the Florida State Seminoles late Saturday night.
"I love the players, coaching staff, program, atmosphere and I feel they put me in the best position to get to where I want to be," Space told Scout.com.
During July, Space emerged as high major prospect and played his way into Scout.com's top 100. A versatile wing, Space shoots the ball well from three, is a willing rebounder and is a solid athlete.
Space is currently rated No. 76 overall and No. 17 at the small forward position.
