Harrison Ingram drove for a tiebreaking layup with 34 seconds remaining and Stanford upset 15th-ranked Southern California for the second time in 16 days, winning 64-61 on Thursday in Los Angeles.

Seeking to double up after a 75-69 home win over the Trojans on Jan. 11, Stanford (12-6, 5-3 Pac-12)found itself in a 60-all tie after a Drew Peterson 3-pointer drew USC (17-3, 7-3) even with 55 seconds left.

After Ingram put the Cardinal up two with his hoop, USC's Isaiah Mobley connected on just the first of two free throws with 14 seconds to go, leaving the Trojans down 62-61.

The win gave Stanford its first season-series sweep of USC since 2014-15. Stanford's Jaiden Delaire and USC's Peterson shared game-high scoring honors with 14 points apiece.

No. 2 Gonzaga 89, Loyola Marymount 55

Keli Leaupepe had 12 points and eight rebounds for Loyola Marymount (9-9, 2-4), which shot just 32.8 percent and was 6 of 22 from 3-point range. The Lions have dropped 32 straight games in Spokane, last winning there in February 1991.

Iowa (14-6, 4-5) struggled to generate offense as conference scoring leader Keegan Murray was saddled with early foul trouble and sat out much of the first half as the Hawkeyes fell behind by 15. Murray recovered in the second half to score 12 of his 14 points to go along with his nine rebounds. He and twin brother Kris Murray, who scored 23 points before fouling out, led the rally that fell short.

No. 7 UCLA 81, Cal 57
