EUGENE, Ore. (AP) -- Fernando Mendoza threw for 215 yards and a key fourth-quarter touchdown and No. 7 Indiana remained undefeated with a 30-20 victory over No. 3 Oregon on Saturday.
Roman Hemby added a pair of scoring runs for the Hoosiers (6-0, 3-0 Big Ten), who frustrated the Ducks (5-1, 2-1) with stout defensive play.
Dante Moore threw for 186 yards and a touchdown for Oregon. He had two interceptions and was sacked six times.
With Oregon down 20-13 going into the fourth quarter, Brandon Finney intercepted Mendoza's and ran it back 35 yards to tie it with 12:42 left.
Mendoza answered with an 8-yard scoring pass to Elijah Sarratt with 6:23 to go. On Oregon's next series, Moore's pass was intercepted by Louis Moore.
Brendan Franke added a 22-yard field goal for the Hoosiers with 2:06 left.
Both sides were coming off weeks off. In their last game, the Ducks beat Penn State 30-24 in double-overtime on the road in the annual White Out game. The Hoosiers beat Iowa 20-15 on the road.
On the first series of the game, the Ducks failed at a fourth-and-1 attempt, giving the Hoosiers good field position for their opening drive. It ended with Nico Radicic's 42-yard field goal.
Oregon pulled ahead with Moore's 44-yard touchdown pass to Malik Benson but Hemby rushed for a 3-yard touchdown before the end of the first quarter to make it 10-7.
Atticus Sappington's 40-yard field goal tied it up for the Ducks, but a later 36-yard attempt that would have given Oregon the lead went wide left.
Franke kicked a 58-yard field goal as time ran out to give Indiana a 13-10 advantage at the break.
Sappington's 33-yard field goal in the third quarter tied it again for Oregon but Hemby added his second touchdown for the Hoosiers, a two-yard dash late in the period.
Oregon will no doubt fall while Indiana will rise in the AP Top 25. The tight game was reminiscent of last year's regular-season showdown between Oregon and Ohio State at Autzen, when the Ducks prevailed 32-31. This game, too, could still have Big Ten title and College Football Playoff implications, but the Ducks don't have the No. 1 Buckeyes on the schedule this year. Neither do the Hoosiers.
