Iowa Coach Lute Olson and Wichita State Coach Gene Smithson both knew a bad mistake had been made, and it led to a 60-56 Shocker upset of the No. 13 Hawkeyes in a wild finish today in the second round of the NCAA tournament.

Another shocker followed, Kansas dumping third-ranked Arizona State, 88-71, behind Tony Guy's 36 points.

Wichita State (25-6) moves on to meet the Jayhawks (24-7) Friday in New Orleans in the Midwest Regional semifinals. LSU, with what is considered a major advantage by playing in the Louisiana Superdome, plays Arkansas in the other game.

With five seconds remaining in today's opening game and the score 56-56, Olson called a timeout when the Hawkeyes had none left. The technical foul sent Randy Smithson to the line and he made both free throws as the Shockers reaped the reward of having rallied from a 40-25 deficit to 40-40 with a 15-0 run during the second half.

"It's obvious we made some mistakes at the conclusion, including some bench mistakes," said Olson. "We had a communications breakdown on the staff. I was told we had one timeout remaining. I indicated to the team we had a bench error at the conclusion that may have cost us the game."

Gene Smithson said he was aware the Hawkeyes were out of timeouts, and when he heard Iowa guard Bob Hansen call one, "I was elated."

"It was a key situation, no doubt," Smithson said.

His son's free throws capped a tremendous Wichita State charge to a berth in an NCAA regional semifinal for the first time since 1965.

At 56-56, Iowa's Kevin Boyle came up short with a 10-foot jumper from the lane with seven seconds left. Shocker forward Antoine Carr rebounded the ball and was fouled by Vince Brookins. As Carr was lining up to take the free throw, Hansen called time -- but the Hawkeyes had used their final allowed timeout with 17 seconds remaining.

Smithson made the score 58-56 and Carr was fouled by Boyle following the ensuing inbound pass. He converted two free throws and Wichita State had avenged an 81-62 setback at the hands of the Big Ten school here last season.

Carr scored 20 points and fellow forward Cliff Levingston 25 as the Shockers eliminated the NCAA's fourth-place finisher of a year ago. Iowa finished this season with a 21-7 record and a three-game losing streak.

Brookins scored 16 points and Steve Krafcisin 13 before fouling out with 5:36 remaining.

Krafcisin made two baskets in the opening 67 seconds of the second half to put Iowa in front, 40-25, but the Hawkeyes proceeded to blow that lead with an ensuing scoring drought of 8:49. Carr scored six points and Levingston five to spearhead the 15-0 spurt by the Missouri Valley champions that tied the game with 10:18 remaining.

The game was tied on four more occasions before Smithson made his two free throws.

Carr and Levingston combined for 14 of Wichita State's final 16 points over the last seven minutes.

In the second game, Kansas consistently befuddled the high-powered Sun Devil offense with a well-disciplined zone defense and held a surprising 45-29 halftime lead.

The Jayhawks took command in the final eight minutes of the first half, outscoring the Sun Devils, 24-8. Arizona State guard Byron Scott, bombing away over the zone at the outset of the second half, trimmed the Kansas lead to nine points. But that was as close as they got as the 6-foot-6 Guy, working inside for six- and eight-footers, helped the lead mount.

John Crawford had 18 points and Darnell Valentine 16 for Kansas. Scott led the Sun Devils (24-4) with 32.
