HOUSTON (AP) — Houston's Case Keenum threw nine touchdown passes to set the Football Bowl Subdivision record for career TD tosses as the 18th-ranked Cougars overcame a slow start in a 73-34 win over Rice on a rain soaked Thursday night.

Keenum threw an interception and had a fumble returned for a touchdown in the first quarter in heavy rain as Rice built a 17-7 lead.

The rain subsided and Keenum and the Cougars got going after that. They outscored Rice 45-3 to take a 52-20 lead by early in the third quarter and cruised to the easy victory to remain undefeated.

Keenum, who became the FBS career leader in total offense last week, has 139 career touchdown passes.

Houston is now in first place in Conference USA's West Division with a 3-0 C-USA record.
