Rodgers ran for a career-high 189 yards and four touchdowns in Oregon State's 38-28 victory over Stanford on Saturday.
The loss snapped a three-game winning streak and dropped the Cardinal (4-2, 3-1) out of the top spot in the Pacific-10 Conference.
Rodgers' four rushing touchdowns in the game matched a school record held by several others. His older bother, James Rodgers, caught five passes for 71 yards and another score for the Beavers (4-2, 2-1).
Gerhart, who was just starting to grab some Heisman buzz, ran for 96 yards and two touchdowns. Going into the game he was averaging 130 yards rushing to rank fourth in the nation.
Jacquizz Rodgers, a 5-foot-7 sophomore who was the Pac-10's offensive player of the year as a freshman, had been frustrated after three straight games with less than 100 yards rushing.
Despite his frustration, Quizz, as he is known, was still averaging 102 yards rushing and 139 total offensive yards going into the game against Stanford.
On a wildcat formation, he broke a 61-yard run early in the game, then plowed into the end zone from 7 yards out on the same drive to give the Beavers an early lead.
Quizz added a 12-yard run before the first quarter ended to make it 14-0. He finished the quarter with 110 yards rushing - his 10th 100-plus yard rushing game overall and fourth this season.
He added a 2-yard scoring run in the second quarter.
With just his second completion of the game, Andrew Luck found Chris Owusu with a 21-yard touchdown pass to make it 21-7.
James Rodgers had a 16-yard touchdown reception before Justin Kahut's 31-yard field goal to make it 31-7 at halftime.
The elder Rodgers brother was chosen a Pac-10 player of the week after 10 receptions for 114 yards and a touchdown in the Beavers' 28-17 upset victory at Arizona State last weekend.
Luck hit Jim Dray with a 7-yard touchdown pass in the third quarter to make it 31-14 before Quizz ran five yards for his fourth TD. That gave him 13 scoring runs for the season.
Gerhart ran for an 11-yard touchdown, as well as the 2-point conversion, and Stanford narrowed it to 38-22 before his 2-yard scoring run in the last minute for the final margin.
Gerhart rushed for 134 yards and three touchdowns in Stanford's 24-16 victory over UCLA last weekend, which sparked both Heisman talk and suggestions that perhaps the Cardinal should be ranked.
He has rushed for 100 or more yards in four of Stanford's games this season, including 200 yards in a victory against Washington.
Sean Canfield completed 22 of 32 passes for 290 yards and a touchdown for the Beavers. Luck was 12 of 30 for 226 yards and two TDs.
Last season, the Cardinal and Gerhart won the showdown between the two running backs in the season opener at Stanford Stadium. Gerhart ran for 152 yards and two touchdowns in the 36-28 victory. Quizz, playing in his first-ever college game, ran for 54 yards.
