UNDATED (AP) – The top-ranked Clemson Tigers and second-ranked Alabama Crimson Tide have earned a trip to Arizona. The two teams will square off in the CFP championship game by dominating the second half of their respective semifinal bowls.

Clemson trailed by a point before outscoring Oklahoma 21-0 in the second half of a 37-17 rout of the fourth-ranked Sooners. Tigers quarterback Deshaun Watson ran for a touchdown and threw for another while rolling up 332 total yards. He completed 16 of his 31 throws for 187 yards, including a 35-yard touchdown to Hunter Renfrow that gave Clemson some breathing room late in the third quarter. The Heisman finalist also ran for 145 yards on 24 carries, scoring the Tigers’ first touchdown on a 5-yard run.

Clemson ran for over 300 yards, with Wayne Gallman carrying 26 times for 150 yards and two scores. Gallman’s four-yard TD run with 10:28 remaining capped the scoring.

Baker Mayfield was 26 of 41 for 311 yards, one touchdown and two interceptions. The Sooners didn’t score after Mayfield hit Mark Andrews for an 11-yard TD with 1:34 left in the first half.

Clemson will carry a 14-0 record into the title game.

The Tide are 13-1 following their 38-0 pounding of Michigan State. Jake Coker shredded the Spartans’ defense by completing 25 of his 30 passes for 286 yards, two touchdowns and no interceptions. Heisman Trophy winner Derrick Henry had a pair of TD runs while carrying 20 times for 75 yards.

Freshman Calvin Ridley grabbed both of Coker’s scoring strikes and had eight receptions for 138 yards.

Connor Cook struggled in leading Michigan State’s attack, going 19 of 39 for 210 yards and two interceptions. Cook didn’t get any help from the Spartans’ running backs, who finished with just 29 yards on 26 carries.

Michigan State’s only trip to the red zone ended with Cyrus Jones intercepting a pass at the goal line late in the first half.
