HOUSTON -- David Mirkovic and Keaton Wagler produced double-doubles as third-seeded Illinois parlayed a 17-0 second-half run into a 65-55 victory over second-seeded Houston on Thursday in the South Regional semifinals of the NCAA Tournament.

The Fighting Illini (27-8) advanced to the Elite Eight for the second time in three seasons. They will face a Big Ten rival, ninth-seeded Iowa (24-12), on Saturday with the winner advancing to the Final Four in Indianapolis.

Wagler responded to a driving layup from Joseph Tugler that pulled the Cougars (30-7) to within 27-26 by sinking a second-chance layup at the 17:37 mark of the second half. That ignited the decisive rally for Illinois, with Jake Davis and Mirkovic adding layups off dribble penetration before Davis knocked down a second-chance 3-pointer that extended the lead to 36-26.

Mirkovic and Ben Humrichous later added 3-pointers as the Illini extended their lead to 44-26. The Cougars went six-plus minutes without scoring before Milos Uzan hit a trey with 11:18 left.

Mirkovic paired 14 points with 10 rebounds. Wagler posted 13 points, 12 rebounds, three assists and two blocks. Andrej Stojakovic scored 13 points off the bench, including nine in the first half to keep the Illini afloat.

Emanuel Sharp led the Cougars with 17 points and led a furious rally that closed the deficit to seven in the waning moments. Kingston Flemings added 11 points, six rebounds and four assists for Houston, which shot just 34.4%.

Only Stojakovic appeared able to play through the first-half slog.

Houston missed its first seven shots yet pulled even at 3-3 when Sharp drilled a 3-pointer at the 15:12 mark, thanks in part to Illinois' 1-for-10 start. Mirkovic lifted the Illini to a 14-10 lead when he followed his trey with a layup, only for Tugler to tie it with consecutive hook shots.

Stojakovic sank a difficult turnaround jumper that beat the shot-clock buzzer, giving Illinois a 21-14 lead. Wagler pushed the Illini to their largest advantage of the first half at 24-16 with a 3-pointer at the 3:23 mark.

The Cougars cut that deficit to 24-22 entering the break when Flemings beat the buzzer with a 3-pointer. Houston shot 27.3% and committed five turnovers in the first half, but the Illini countered with 35.7% shooting and scored only two points from seven offensive rebounds.
