USC swiped a major commitment in Ohio State territory signing four-star lineman Aundrey Walker, who announced his decision at the Glenville High (Cleveland, Ohio) signing ceremony Wednesday morning.

Glenville has traditionally sent a number of players to Ohio State, but Walker spurned offers from the Buckeyes and Michigan State, choosing to don a Trojans' cap.

USC needed help on the offensive line and Walker could provide that. At 6-foot-5, 355 pounds, he will definitely be providing some size.

Walker is ranked as the No. 1 guard by Rivals, No. 9 by Scout and No. 15 by ESPN.
