Kenny Fields scored 21 points and Darren Daye 20 to lead fourth-ranked UCLA to a 75-66 victory over No. 7 Iowa yesterday at UCLA.

Trailing, 20-17, after 11 minutes, the Bruins (5-0) outscored Iowa, 19-2, in a 7:02 span to take a 36-26 lead at the half. Iowa (6-1) scored 11 of the first 13 points in the second half and cut the margin to 65-64 with 1:58 left.

Fields then scored two quick baskets to put the Bruins up by five. After Bob Hansen made a jumper for Iowa, reserve guard Michael Holton scored six points in the final 17 seconds for the Bruins.

Iowa was led by Greg Stokes with 27 points and Hansen with 18.

"We had some mistakes at critical times and opportunities we didn't cash in on," said Iowa Coach Lute Olson. "This game was a valuable experience for us. I'd rather lose here under these circumstances than win by 30 points somewhere else and not learn anything. I think the Bruins deserve their ranking."

There was some confusion in the closing seconds when Stokes drew an offensive foul, his fifth foul of the game, with the Hawkeyes trailing, 69-66. The officials gave the ball to UCLA, but did not stop the game. Only after Olson complained and drew a technical was Stokes replaced.

"The officials are not supposed to start the game until he is replaced," said Olson. "Greg was still on the floor, so we only had four active players. They scored five against four, but that had no real bearing on the outcome."
