AMES, Iowa - Steele Jantz threw for 281 yards and Shontrelle Johnson rushed for a career-high 120 yards to help Iowa State (1-0, 0-0 Big 12) down Tulsa, 38-23 in the season-opener at Jack Trice Stadium Saturday afternoon.



Jantz tossed two touchdown passes and ran for another, as the Cyclones racked up 441 yards of total offense in front of 54,931 fans, the largest crowd to ever see an Iowa State home opener.



Iowa State took a 24-16 lead at the break, scoring 17-straight points. Jantz hit Josh Lenz on a 43-yard toss for the first score of the game to move Iowa State out in front 7-0.



Tulsa battled right back with 16-straight points to forge a 16-7 lead. Ja'Terian Douglas scored on a 1-yard touchdown run followed by a six-yard touchdown catch by Thomas Roberson after a Cyclone turnover.



The Cyclones responded, however. Jake Knott forced his ninth career fumble, knocking the ball loose from Bryan Burnham to thwart a Tulsa drive and switch the momentum. Iowa State proceeded to go on an eight-play, 51-yard drive capped off by a Jantz 5-yard dash to trim the Tulsa lead to 16-14 with 11:55 left in the first half.



Jantz then connected on his second touchdown pass on Iowa State's next possession, finding Ernst Brun in the end zone from seven yards out to make it 21-16 Iowa State. Edwin Arceo kicked a 30-yard field goal as the first half expired to give the home team a 24-16 lead at the break.



Jantz was 22-of-30 for 240 yards in the first half, accounting for all three of Iowa State's touchdowns.



The Cyclones made it 24 unanswered points with an impressive drive in the third quarter. Iowa State mounted a 12-play, 82-yard drive culminated by a James White 6-yard run to go up 31-16. Iowa State churned out 61 yards on the ground on the drive, including 32 from Johnson.



Tulsa made it interesting in the fourth quarter, cutting the gap to 31-23 after a 77-yard run by Trey Watts set up a Keyarris Garrett 4-yard touchdown grab.



Deon Broomfield made the big play late, intercepting a Cody Green pass and returning it 51 yards to the Tulsa 5-yard line. Johnson scored on the next play to seal the victory for the Cyclones.



Iowa State won the turnover battle, forcing three turnovers and committing just one. Durrell Givens had a fumble recovery and an interception in the game.



Lenz ended the game with eight catches for 96 yards and Chris Young caught seven balls for a career-high 73 yards. Knott totaled a team-high 11 tackles.



Iowa State is back in action next weekend, traveling to Iowa City to face Iowa in a 2:30 p.m. kickoff on the Big Ten Network.
