AMES, Iowa (AP) – Bryce Petty threw for 336 yards and a touchdown and ran for a pair of TDs as seventh-ranked Baylor cruised past Iowa State 49-28 in its Big 12 opener Saturday night.

Shock Linwood had three TDs rushing for the Bears (4-0, 1-0 Big 12), who have started 4-0 in back-to-back seasons for the first time in 76 years.

Baylor’s first game against a Power 5 school was a bit more difficult than its first three against weaker competition. But the Bears jumped ahead 35-7 late in the second quarter and led by at least 21 points for the entire second half.

Quarterback Sam Richardson threw for 212 yards and ran for 99 more for Iowa State (1-3, 0-2), which is 0-3 at home.
