Indianapolis ? Dan Miller matched a career high with 23 points, helping Notre Dame move into the round of 16 with a 68-60 victory Saturday over Illinois in the West Regional.

“We were running and firing and I did not want to stop us because we were going for it,” Irish coach Mike Brey said

Notre Dame will travel to Anaheim, Calif., to play No. 1 seed Arizona.

Chris Thomas added 17 points for the fifth-seeded Irish, who had not advanced this far in the NCAAs since 1987 under coach Digger Phelps. That year, they were eliminated in the regional semifinals by North Carolina.

It was a disappointing second-round exit for fourth-seeded Illinois (25-7), the Big Ten tournament champions. Big Ten player of the year Brian Cook had 19 points and 16 rebounds.

The Illini trailed by 13 at halftime but cut it to six with 1:45 left after Deron Williams’ tip in. They didn’t score again.

Williams went end-to-end after a steal but missed the layup, and Chris Quinn’s two free throws with 27 seconds left sealed the victory.

The Irish (24-9) lost in the second round the last two years — without Miller, a transfer from Maryland.

He shot 5-of-7 from long range as Notre Dame set a school tournament record with 13 three-pointers. The Irish were 13-for-24 from beyond the arc, topping their previous high of 10 set last year against Charlotte.

“When the big guys played off me, I shot it. When they came up on me, I tried to drive by them,” Miller said. “When I got that stretch going, they were playing off me so I just pulled the trigger on them.”
