LAS VEGAS (AP) — Evan Mobley scored 13 of his 26 points in the two overtimes and No. 24 Southern California outlasted scrappy Utah 91-85 in the Pac-12 quarterfinals. The second-seeded Trojans had a hard time shaking the seventh-seeded Utes in a game filled with methodical possessions. Utah hung around after trailing by 10 midway through the second half and rallied to tie the game on Ian Martinez’s two free throws with 2.3 seconds left in regulation. The Utes tied it again in the first overtime on Alfonzo Plummer’s 3-pointer with 24 seconds left. Mobley had five points in the first overtime and eight more in the second to send the Trojans into Friday’s semifinals against the California-Colorado winner.
