SAN DIEGO (AP) — Bennedict Mathurin made a 3-pointer to force overtime and scored six more points in the extra session, and top-seeded Arizona outlasted ninth-seeded TCU 85-80 in the second round of the NCAA Tournament. Mathurin finished with 30 points and Christian Koloko scored 28, including a putback dunk that slammed the door on the Horned Frogs with 9 seconds left in OT. Arizona’s two stars did enough for the Wildcats to avoid becoming the second No. 1 seed to fall during this tournament's opening weekend. They will face fifth-seeded Houston in the Sweet 16. Chuck O’Bannon Jr. had 23 points for TCU.
