Lahaina, Hawaii ? Iowa stayed close in the first half against Louisville on Monday in the opening round of the Maui Invitational, then dominated the next 20 minutes.

Jeff Horner scored 11 points in a 4 1/2-minute span of the second half, part of a nine-minute stretch when Iowa held No. 12 Louisville without a field goal, and the Hawkeyes went on to a 76-71 victory.

“I thought in the second half we performed extremely well,” Iowa coach Steve Alford said. “I thought our defense went to another level and we executed offensively.”

That happened after a challenge from the coach to his players.

“At halftime I told them we were down four points to a team that shot 61 percent. I told them they weren’t going to shoot 61 percent again so we had to step up, concentrate and play defense,” Alford said. “I really challenged Jeff, Adam (Haluska) and Pierre (Pierce). I wouldn’t trade those three guys for anybody and I thought in the first half they weren’t themselves. They did what we knew they would, they responded to the challenge.”

Now Iowa (2-0) will play No. 15 Texas in the semifinals today. The Longhorns (2-0) beat Chaminade, 84-62, Monday.

Juan Palacios scored inside with 11:39 to play to give Louisville (1-1) a 48-42 lead. That was the Cardinals’ last field goal for nine minutes as Iowa went up 67-56. Louisville missed 10 shots in that span and managed just eight points, all on free throws.

Francisco Garcia had 17 points for the Cardinals, who finished 7-for-23 from three-point range. Ellis Myles added 12 points and eight rebounds.

“We didn’t pass the ball very well,” Garcia said. “We weren’t focused on offense and we tried to do too much for ourselves.”
