Clint Chelf completed 17-of-22 passed for 197 yards and three touchdowns to lead Oklahoma State to a 58-14 win over Purdue in the Heart of Dallas Bowl.
Charlie Moore, Blake Jackson and Blake Webb each caught touchdown passes for the Cowboys (8-5), who won their third bowl game in as many seasons.
J.W. Walsh also threw for a pair of scores while Isaiah Anderson and Jeremy Seaton also added receiving touchdowns in the triumph.
"Obviously, a very good game for our team. Our players competed, had really good preparation over the last three weeks," said Oklahoma State head coach Mike Gundy. "We did a great job taking care of the football and forced turnovers, took advantage of those turnovers. We had a number of players that played very well."
Robert Marve for threw for 212 yards, two touchdowns and two interceptions and Brandon Cottom and Tommie Thomas each added a receiving score for the Boilermakers (6-7), who had a three-game winning streak and two-game bowl- winning streak.
"We just ran into a very good football team today," said Purdue head coach Patrick Higgins. "As you know, when you play a quality opponent like Oklahoma State, when you turn the ball over five times, you don't take advantage of your opportunities, the game can turn out like this."
Chelf's 4-yard touchdown pass to Moore put the Cowboys up 7-0.
Marve's pass on the ensuing touch was intercepted by Shamiel Gary and returned to the Purdue 26. Three plays later, Chelf found Johnson in the back of the end zone for a 7-yard touchdown pass.
Walsh's 16-yard touchdown pass to Seaton gave OSU a 21-0 with 14:22 left until half. Chelf guided Oklahoma State down to the Purdue 16-yard line, before the Cowboys brought in Walsh, who threw his 12th touchdown pass of the season.
Smith's 5-yard touchdown run capped a seven-play, 72-yard drive to push the OSU spread to 28-0.
Daytawion Lowe recovered O.J. Ross' fumble and returned it 37 yards for a touchdown to make it 35-0 early in the third quarter.
The Cowboys forced a Purdue punt and drove down to the Boilermakers' 3-yard line, but couldn't crack the goal line on 3rd-and-goal and settled for Quinn Sharp's 20-yard field goal.
Chelf's 37-yard pass to Anderson pushed the Cowboys' spread to 45-0.
Purdue finally got on the board when Marve connected with Cottom for a 32-yard touchdown. Marve faked the handoff and rolled to his right before throwing across field to a wide-open Cottom.
Oklahoma State, though, came right back with a 21-yard field goal to give the Cowboys a 48-7 advantage with 11:21 to play.
The Cowboys cashed in on another Purdue turnover when Walsh found Webb for a 37-yard touchdown, the freshman receiver's first career touchdown reception.
Sharp's 42-yarder put OSU up 58-7 and Marve's 16-yard pass to Thomas accounted for the final margin.
