Adam Robinson rushed for a career-high 156 yards and a touchdown on 14 carries as No. 9 Iowa crushed Iowa State 35-7 Saturday for its third straight win over the rival Cyclones.

Ricky Stanzi threw two touchdown passes and ran for another score for the Hawkeyes (2-0), who scored touchdowns on four of their first five drives.

Stanzi threw short TD passes to Marvin McNutt and Allen Reisner, and his 1-yard TD plunge gave Iowa a 28-0 lead at halftime.

Jewel Hampton, playing his first game since 2008, added a 2-yard touchdown run in the second quarter. Robinson's 39-yard touchdown run made it 35-0 in the third quarter.

Iowa State's Austen Arnaud threw three interceptions in the third quarter and finished 20 of 44 for 197 yards. The Cyclones (1-1) scored their first touchdown against Iowa since 2006 on Arnaud's 8-yard TD pass to Darius Darks with 1:51 left.

This used to be a surprisingly close rivalry, with Iowa State taking seven of the last 12 entering play. But the series has swung back in Iowa's favor over the last two seasons.

Iowa thumped the Cyclones 35-3 on the road last year, and the Hawkeyes looked remarkably efficient in burying Iowa State.

Iowa had scored 70 unanswered points on Iowa State until Arnaud's touchdown toss in garbage time.

Iowa scored a touchdown on its opening possession for the second straight week, capping a 13-play drive on Stanzi's 9-yard TD pass to McNutt.

The Hawkeyes forced Iowa State into a quick three-and-out and went 71 yards in 16 plays, with Hampton's touchdown putting Iowa on top 14-0.

Karl Klug then sacked Arnaud to force another punt, and Stanzi found McNutt for a 66-yard completion and Reisner for a 2-yard TD pass that put the Hawkeyes ahead 21-0 with 10:02 left in the first half.

The Hawkeyes had outgained Iowa State 222 to minus-2 yards to that point and held the ball for nearly 18 of the first 21 minutes.

The nightmare only worsened for the Cyclones late in the second quarter. Robinson took a draw 75 yards to the Cyclones 1, and Stanzi's plunge gave Iowa a 28-0 lead with 2:52 left in the first half.

Stanzi finished 11 of 18 passing for 204 yards.

Alexander Robinson had 48 yards rushing for Iowa State, which looked impressive in dispatching of Northern Illinois 27-10 last week. But the Cyclones had no answer for the Hawkeyes on either side of the ball once again, gaining just 275 yards of offense and allowing Iowa to score TDs on all four of its red-zone possessions.

Hampton rushed for 463 yards and seven touchdowns as a true freshman in 2008. He redshirted last season following knee surgery and was suspended for last week's game disciplinary reasons.

Hampton, who split carries with Robinson, rushed for 84 yards on 20 carries.

Iowa hadn't won three straight over Iowa State since 1997, the last of 15 consecutive victories over the Cyclones.
