Kenny Hill threw for 452 yards and two second-half touchdowns, including a 75-yarder to John Diarse on the first play after halftime, and TCU pulled away from SMU 33-3 on Friday night.
Diarse’s catch-and-run score on a quick slant came after he left the game in the second quarter following a hard hit from Darrion Millines that led to a targeting ejection for the SMU safety.
Millines delivered the hit in the end zone after Anthony Rhone’s interception in front of him, leaving a staggered Diarse on two knees as athletic trainers and coach Gary Patterson came out to check on him.
Diarse came back later in the second quarter to catch a 23-yard pass on the drive to a field goal that put TCU ahead for good in a fifth straight victory over the Mustangs and the 15th win in the past 17 meetings between the crosstown rivals.
The junior had a career high in yards receiving for the second straight week, finishing with 139 on six catches.
SMU (2-2) played a touchdown-free first half against a high-scoring Big 12 team for the second time this season, trailing 6-3 at the half following a 6-6 halftime tie against No. 16 Baylor in Waco two weeks ago. The Bears went on to a 40-13 win.
The Horned Frogs (3-1) scored touchdowns on their first two possessions after halftime, the second on Hill’s perfect fade pass to Jaelan Austin from the 2 for a 20-3 lead. Hill was 31 of 45 with an interception.
TCU kicked four field goals, two each from Brandon Hatfield and Ryan Graf, who just cleared the crossbar on a career-long 46-yarder.
