HOUSTON — The Houston defense continued to make a difference on Saturday.
The Cougars' offense struggled for the better part of three quarters, but the defense did what it has done so far this season — create turnovers.
John O'Korn threw for 198 yards and a touchdown, Kenneth Farrow ran for two second-half touchdowns and unbeaten Houston forced four turnovers to defeat Memphis 25-15.
O'Korn finished 13 of 30 and wide receiver Deontay Greenberry caught four passes for 76 yards for the Cougars, who remained tied for first in the league despite being outgained 349-247.
Houston, 5-0 for the fourth time, tied its win total from last year (5-7). The Cougars have forced 18 turnovers this season.
"It wasn't pretty," coach Tony Levine said. "It wasn't perfect. It may never be perfect. I am really proud of our defense creating those four turnovers."
Paxton Lynch was 21 of 41 for 222 yards for the Tigers, who lost four fumbles. Jake Elliot tied a school record set by Ryan White in 1999 with five field goals for Memphis.
"Obviously, offensively you can't kick field goals every time you get the ball down there close," Memphis coach Justin Fuente said.
