IOWA CITY - Boston University had No. 9 Iowa reeling early in the game and Chauncey Leslie knows why.
"We came out big-headed, we came out here partying and they took it to us," the Iowa guard said.
Boston University led for much of the first half behind Matt Turner's torrid shooting, but Iowa eventually got him under control and pulled away to a 90-61 victory Wednesday night in the second round of the Guardians Classic.
In a game that had five technical fouls, Iowa didn't take the lead for good until the final minute of the first half and finally subdued its feisty opponent with a 19-4 second-half run.
The Hawkeyes will play No. 12 Memphis in the semifinals of the tournament in Kansas City on Tuesday.
"I thought this was a good game for us," Iowa coach Steve Alford said. "To start the way we started, have our players not ready and having that Turner kid hot in the first half and then make a 40-point turnaround, that says something about our team."
Luke Recker struggled with his shooting, going 5-for-16, but still led Iowa with 18 points. Reggie Evans, held to five points and two rebounds in a frustrating first half, finished with 16 points. Leslie came off the bench to get 15 points, three steals and four assists.
Turner scored the game's first eight points and had 19 in the first half on 7-for-11 shooting. But Leslie teamed with other defenders to shut him down after the that and he went 1-for-6 in the second half to finish with 21 points.
"That's what they recruited me for, to go out and play defense," Leslie said. "That's what I try to do on the court and it happened tonight."
Glen Worley scored 11 points for Iowa and Recker had 10 rebounds. Chaz Carr scored 15 for Boston University.
"Obviously, Iowa has a very good team," Boston University coach Dennis Wolff said. "I think they wore us down. Up until about the 12-minute mark, I was happy with the way we competed and then I think we got tired and made a lot of tired type of plays."
Iowa closed the first half with a 6-0 run to take a 43-37 lead, Rod Thompson scoring on a rebound shot at the buzzer. A two-handed dunk by the 5-foot-9 Turner left Boston University trailing 45-44 early in the second half, but the Terriers got only two baskets over the seven minutes and Iowa broke it open.
Recker hit two 3-pointers, Worley sank one and Leslie dunked after a steal as Iowa built a 59-46 lead. Evans then scored five points and Leslie, who was 7-for-9, added a 3-pointer to increase the lead to 67-48 with 9:49 to play.
Boston University was wearing down by then and never threatened again.
All of the technical fouls came in the first half and each team had a five-point possession.
Evans completed a three-point play after Recker sank two free throws for a technical on Jason Grochowalski. That got the Hawkeyes back into the game quickly after they trailed 13-5.
With Iowa leading 19-18, Evans was called for a personal foul and then a technical. Boston University kept the ball after Carr sank two free throws for the T and Ryan Butt hit a 3-pointer, giving the Terriers a 23-19 lead.
Iowa's Jared Reiner was given a technical for hanging on the rim and Iowa's Duez Henderson and Turner both were assessed technicals after they crashed into a table while pushing each other as they battled for a loose ball.
Wolff blamed the technicals on frustration.
"I don't think they thought we were any good," he said. "So then they got a little frustrated and then our guys got frustrated. I don't think we have the same type of team as Iowa, but I think we have a decent team. And we didn't come in here to be pushed around."
