Four-star offensive tackle Dylan Wonnum announced his commitment to South Carolina on Saturday via Twitter, four days prior to National Signing Day.
The Georgia native ranks as the No. 13 offensive tackle and the No. 178 overall prospect for the 2018 national recruiting cycle, according to the 247Sports Composite.
Wonnum, an Under Armour All-American, narrowed down his choices to Auburn, South Carolina and Tennessee and made official visits to all three schools in January.
The four-star prospect will join former high school teammates Aaron Sterling, a rising sophomore and fellow incoming freshman Josh Vann in Columbia next season.
South Carolina currently has 22 commitments and 19 signees for its 2018 national recruiting class, which ranks No. 20 overall, according to the 247Sports Team Composite.
