Quick-strike, big plays in the first half, then steady clock-eating scoring drives in the second half powered TCU to a 42-9 win over Oklahoma State at Amon G. Carter Stadium in Fort Worth, Texas, Saturday, ending OSU's 5-game winning streak.
Both teams picked up one first down then had to punt on their opening possession.
On OSU's second possession, Daxx Garman was intercepted by Kevin White at the OSU 48-yard line.
It took TCU just two plays to score, with B.J. Catalon scoring on a 34-yard touchdown run to make it 7-0 Horned Frogs with 9:23 to play in the first quarter.
OSU lost a yard on their next series and punted to the Horned Frogs.
This time it took TCU just one play to score, with Trevone Boykin passing to Josh Doctson for a 77-yard touchdown to double the lead, 14-0 with 7:42 to play in the first quarter.
The Cowboys then got their first big offensive play, with Garman going deep to Brandon Sheperd for 57 yards.
That was Garman's highlight of the game; he was just 10 of 25 passing for 132 yards.
The drive stalled from there, and Ben Grogan kicked a 30-yard field goal to make it 14-3 TCU with 5:20 to play in the opening quarter.
TCU only took two plays to answer, with Boykin passing to Doctson, who outleaped OSU safety Jordan Sterns to make the catch, then raced 84 yards for the touchdown to make it 21-3 Frogs with 4:41 left in the first quarter.
Doctson had 7 catches for 225 yards.
The next time TCU got the ball, OSU made a stop, as James Castleman made a tremendous catch to intercept Boykin at the line of scrimmage at the OSU 42.
The Cowboys threatened to get their first touchdown, but had to settle for a 27-yard field goal from Grogan to make it 21-6 TCU with 13:26 to play in the first half.
It looked like OSU's defense was going to make a big play, but on a tipped pass, Trey Flowers dropped an easy catch for an interception and TCU ended up punting on the drive.
The Cowboys marched to yet another field goal, as Grogan kicked a 28-yarder to make it 21-9 TCU.
After holding TCU without a first down on their first two possessions of the second quarter, OSU allowed the Frogs to extend the lead late in the first half.
On 4th and inches in OSU territory, TCU went for it, and B.J. Catalon not only got the first down, but raced 35 yards for the touchdown and a 28-9 lead with 1:53 to play in the half.
Catalon had 102 yards rushing on 10 carries.
The Frogs got the ball back with just under a minute left in the half, but Jaden Oberkrom missed a 48-yard field goal attempt.
TCU got the ball to start the second half and marched 79 yards to a touchdown, with Boykin passing to Deante' Gray for a 22-yard touchdown to make it 35-9 Frogs with 9:49 left in the third quarter.
Boykin set a career high for passing yards with 410 on 26 of 39 passing.
TCU's next possession was similar, this time the Frogs went 88 yards in 12 plays, with Aaron Green finishing it off with a 4-yard touchdown run to put TCU up 42-9 with 2:41 left in the third quarter.
OSU couldn't generate much offense in the fourth quarter either.
Garman had a pass intercepted by Derrick Kindred, and the Cowboys had just two first downs in the second half.
OSU had their streak of scoring at least 20 points in a game end at 58, the second longest streak in major college football history behind 63 by USC.
TCU outgained OSU 676 to 258 in total yards.
The Cowboys drop to 5-2, 3-1 in Big 12 play, while TCU improves to 5-1, 2-1 in conference play.
OSU hosts West Virginia, who upset Baylor Saturday, in a game next Saturday at 2:30 in Stillwater.
