Gray, a four-star prospect and the No. 8 offensive tackled in the 2013 class, committed to Maryland on Friday.
It is the latest coup for Maryland coach Randy Edsall and his staff since offensive coordinator Mike Locksley joined the staff offseason.
The 6-foot-5, 265-pound Gray played only in the season opener last year at Dunbar High (Washington, D.C.) because of eligibility issues and he transferred to Edison Friendship in the winter.
he is the fifth member of the class, and third from Maryland, joining Wicomico High (Salisbury) defensive end Derrick Hayward and The Gilman School (Baltimore) quarterback Shane Cockerille as in-state commits.
