AMES, Iowa (Ticker) -- Iowa State had not been ranked in two years. Seneca Wallace did his best to ensure the Cyclones' stay in the top 25 would not end after just one week.
Wallace threw for three touchdowns and ran for another as the 24th-ranked Cyclones manhandled Troy State, 42-12.
One week after throwing for a career-high 361 yards in a 36-31, come-from-behind win over intrastate rival Iowa, Wallace connected on 17-of-25 attempts for 295 yards without an interception.
Iowa State (4-1) notched its fourth consecutive victory since a narrow defeat to Florida State in its season opener.
The Cyclones, who last were ranked at the end of the 2000 season, limited the Trojans (1-3) to 107 yards rushing. Last week, Troy State ran for a school-record 464 yards in a blowout of Southern Utah.
Iowa State, which never trailed, took a 7-0 lead just 2:01 into the contest when Andy Kohler ran a blocked punt in for a touchdown. The Cyclones took a 21-6 advantage into halftime after Wallace connected on a 54-yard pass to Lane Danielsen with 30 seconds remaining in the second quarter.
Wallace added touchdown tosses of 20 and five yards - both to Lance Young - in the first 8:13 of the third quarter to turn the game into a rout.
Trojans signal-caller Hansell Bearden was 17-of-35 for 195 yards and ran for a touchdown in the loss.
