SPOKANE, Wash. — Xavier Thames scored 30 points, and fourth-seeded San Diego State reached the round of 16 for the second time in school history, ending the run of No. 12 seed North Dakota State 63-44 on Saturday in the third round of the NCAA tournament.

The Aztecs (31-4) now get to make the short drive up the interstate to Anaheim, Calif., where they will face either No. 1 seed Arizona or eighth-seeded Gonzaga in the West Regional semifinals on Thursday.

Thames, who was 9 of 19 from the field, had five assists and ended the comeback hopes of the Bison with a six-point spurt late in the second half.

Dwayne Polee II was the only other San Diego State player in double figures with 15 points.

Kory Brown led the Bison (26-7) with 13 points, but the best shooting team in the country shot only 31.9 percent.
