Alabama scored a commitment from one of the top defensive back recruits in the nation.

Four-star safety Ronnie Harrison announced his decision on Tuesday. The 6-foot-3, 205-pound player is rated as the No. 185 prospect in the nation and the No. 20 player in the state of Florida by the Rivals recruiting rankings.

Harrison stars for Florida State University School in Tallahassee. He chose Alabama over offers from LSU and North Carolina.

He's the 20th commitment from the Tide's 2015 class.
