LaQuinton Ross hit the tiebreaking 3-pointer with 2 seconds to play, and Ohio State advanced to the brink of its second straight Final Four appearance with a 73-70 victory over Arizona on Thursday night in the West Regional semifinals.

Ross, the Buckeyes’ remarkable reserve, scored 14 of his 17 points in the second half for the second-seeded Buckeyes (29-7), who rallied from an early 11-point deficit and weathered the sixth-seeded Wildcats’ late charge for their 11th consecutive victory since mid-February.

Deshaun Thomas scored 20 points for Ohio State, and Aaron Craft added 13 before ceding the Buckeyes’ final shot to Ross. Craft hit an awfully similar 3-pointer against Iowa State last Sunday to send the Buckeyes forward.
