Iowa State (6-2) improved to 6-1 in the Big 12, matching the school record for conference wins.

Kansas State sputtered with quarterback Will Howard, who completed just three of his first 9 attempts and was replaced after throwing an interception late in the second quarter.
Purdy, who finished 16 for 20, also ran seven times for 59 yards.
Iowa State outgained the Wildcats 539-149.
