Before Ryan Day officially takes over as head coach on Jan. 2, he has earned the commitment of the most important recruit in the upcoming 2019 class.

On Wednesday, defensive end Zach Harrison announced his commitment to Ohio State.

Harrison, a five-star recruit and No. 4 member of his class, according to 247 Composite Rankings, is the highest-ranked recruit in Ohio State’s 2019 class, which ranked No. 10 in the NCAA prior to Harrison’s signing.

A 6-foot-5, 243-pound strong-side defensive end at Olentangy Orange High School, Harrison is the top-ranked recruit from Ohio and visited Michigan and Penn State before ultimately choosing the Buckeyes.

Harrison is the top-ranked strong-side defensive end in his class, and joins wide receiver Garrett Wilson and center Harry Miller as the five-star recruits Ohio State has committed for the class of 2019.
