David Mirkovic elevates for a huge block for Illinois. (0:16)
HOUSTON -- David Mirkovic had 14 points and 10 rebounds, and third-seeded Illinois flexed its defensive muscles to eliminate last year's national runner-up from the NCAA tournament, beating Houston 65-55 in the South Region semifinals on Thursday night.
Next up is a meeting Saturday with ninth-seeded Iowa to see which Big Ten team will advance to the Final Four. It will be the 11th Elite Eight appearance for Illinois (27-8) and its second in three seasons under Brad Underwood.
In the Sweet 16 for a seventh consecutive time, the second-seeded Cougars (30-7) were thrilled to be playing just over two miles from their campus. But their poor shooting gave Houston fans little to cheer about and delighted the orange-clad Illini faithful who made the long trip to Texas.
"At the beginning of the game Houston fans were a little louder, but as game was going, [our fans] started being louder in their city," Mirkovic said. "So it's just really important for us, I would say just like a wind to our back. They pushed us, and thanks for them."
Star freshman point guard Kingston Flemings, who is expected to be an NBA lottery pick, had 11 points on 4-of-10 shooting. Milos Uzan made just 2 of 11 shots.
But they were far from the only Cougars who struggled offensively. The team shot just 34% in its lowest-scoring game of the season.
Underwood was asked about his team's defensive performance.
"I think it's a mental focus," he said. "We've been very good at times defensively. It's just sustaining it. We've got very capable defenders, we've got size and length, and we just got to make shots difficult."
Illinois finished well under the 84.7 points a game it averaged entering Thursday. But its offense was still plenty powerful enough to send Houston back to its nearby campus. Keaton Wagler had 13 points and a team-high 12 rebounds for the Illini; he and Mirkovic became the first pair of freshman teammates to each have a double-double in the same NCAA tournament game since freshmen became fully eligible in 1972-73, according to ESPN Research.
"Coaches were telling us before the game: 'It's going to be a guard game to get rebounds. We need 10-plus out of the guards,'" he said. "So I took that challenge on. I went in there, tried to play as tough as I could, not let them get any second-chance rebounds. I went in there and tried to get every rebound I could."
Andrej Stojakovic -- with his dad, three-time NBA All-Star Peja Stojakovic, in the stands -- also scored 13.
By the time the final seconds ticked off the clock, many Houston fans had cleared out and the Illinois supporters stood and cheered as their team celebrated.
"I was proud of our kids' effort," Houston coach Kelvin Sampson said. "We just didn't play good enough."
The Illini were up by one early in the second half when they broke it open with a 17-0 run for a 44-26 lead with about 12 minutes left. Jake Davis scored five points during the burst, including a 3-pointer, and Mirkovic and Ben Humrichous capped it with consecutive 3s.
The Cougars missed seven consecutive shots as Illinois built its lead. When Uzan finally ended Houston's drought with a 3-pointer with 11:20 left, it had been almost seven minutes since the team had scored.
"We were getting stops and we were limiting them to one shot, and to tough shots as well," Wagler said. "Making them shoot tough middies or contested at the rim, 3-pointers, all of that, and then we were going in and grabbing the rebound and offensively we were getting the shots that we wanted, we were knocking them down."
Consecutive 3-pointers by Chase McCarty got Houston within nine with about six minutes left. But Wagler and Tomislav Ivisic made 3-pointers to fuel an 8-0 run that extended the lead to 58-41.
