No one has slowed down Central Florida this season, except Mother Nature. She did it again Saturday, but not before the Knights unleashed an offensive performance their coveted young coach deemed "special."

McKenzie Milton threw five touchdown passes -- three to receiver Tre'Quan Smith -- as No. 25 Central Florida remained unbeaten with a 51-23 rout of Cincinnati on Saturday night in an American Athletic Conference game shortened by weather at Nippert Stadium in Cincinnati.

Smith finished with 165 yards on five receptions and also scored a rushing touchdown for the Knights, who improved to 4-0 for the first time since 1988, when UCF was still in Division II.

UCF did not punt and scored on all eight of its possessions.

Milton completed 16 of 19 passes for 374 yards but didn't get a chance for more in the fourth quarter. Lightning and heavy rain moved into area, and the game was stopped with four seconds left in the third quarter and Central Florida leading 51-23.

Officials waited an hour before calling the game. Cincinnati coach Luke Fickell said he didn't want to stop the game, but understood it was for the safety of the athletes.

UCF's season has been severely hampered by weather. Three of the Knights' games were cancelled by Hurricane Irma. But it hasn't stopped Central Florida from putting up big numbers under second-year coach Scott Frost.

The Knights (4-0, 2-0 AAC) racked up 515 yards of offense in just three quarters.

"I've been around football for quite a while, and I don't remember a cleaner game on offense," Frost said. "They executed so well. We had such a good week of preparation, and I knew they were ready to play. But the performance that they put up on offense is special."

Frost, a former offensive coordinator at Oregon, has become a hot prospect with the Knight's hot start and prolific offense.

Cincinnati quarterback Hayden Moore ran for two touchdowns and threw for one to lead the Bearcats (2-4, 0-2), who lost their third straight game.

Moore completed 23 of 40 passes for 278 yards and also led the Bearcats with 75 yards rushing.

"On the positive side of things, our offense did a good job," Fickell said after the loss. "They moved the football, even when they didn't score, they moved the ball moved the football.

Milton completed 10 of 12 passes for 282 yards and four touchdowns in a dominating first half filled with big plays.

The Knights scored touchdowns on the first three possessions. Milton threw a 54-yard touchdown pass to Dredrick Snelson and followed it with a 79-yard completion to Smith to put the Knights up 14-0 five minutes into the game.

Senior tight end Michael Colubiale also caught a touchdown pass from Milton, and running back Taj McGowan had a short touchdown run for the Bearcats.

"Those guys just make plays after plays when you get the ball in their hands," Milton said about his plethora of weapons.

Moore tried to keep the Bearcats in the game, more with his legs than his arm. The junior quarterback had two touchdown runs in the first half, including a 16-yard scamper down the sideline that trimmed UCF's lead to 30-13 with 3:57 left in the second quarter.

"We got to continue to grow," Fickell added. "It's a roller coaster."

Milton hooked up with Smith again for a 41-yard touchdown and the Knights went into halftime with a commanding 37-16 lead.

The Knights possessed the ball for just over 10 minutes in the first half, yet racked up 385 total yards.
