K.J. Costello overcame a rough start to throw two touchdown passes to JJ Arcega-Whiteside and No. 9 Stanford beat FCS-level UC Davis 30-10 on Saturday.
Costello threw interceptions on two of the first three drives of the game for the Cardinal (3-0) before settling in a bit against the overmatched Aggies (2-1).
The game kicked off at the unusually early time of 11:01 a.m. local time in front of a sparse crowd at Stanford Stadium. The Cardinal even played without star running Bryce Love, who got the week off to heal some minor ailments.

Jake Browning threw for 155 yards, a touchdown, and an interception. Aaron Fuller led the way with 108 yards on six catches. Washington (2-1, 1-0 Pac-12) beat the Utes for a third straight season, and holds an 11-1 lead in the all-time series.

The Aztecs (2-1) beat the Sun Devils (2-1) for the second straight year. This one spoiled the homecoming of new ASU coach Herm Edwards, who played his final college season with the Aztecs in 1976 and then graduated from SDSU with a degree in criminal justice.

at Nevada 37, Oregon State 35: Jordan Choukair missed a 33-yard field goal as time expired and Nevada held off a furious Oregon State comeback to win 37-35 on Saturday night.
Nevada (2-1) led 30-7 lead with 10:16 left in the second quarter after Asauni Rufus forced Conor Blount to fumble the ball, and Malik Reed picked it up and ran 48 yards for a touchdown.
After the defensive touchdown, Oregon State (1-2) replaced Blount at quarterback with Jake Luton, who left the season opener two weeks ago with a concussion against No. 4 Ohio State.
