TUCSON, Ariz. – Senior quarterback Jerrard Randall accounted for 242 yards of total offense and added two touchdowns, but the Arizona Wildcats dropped their Homecoming game to Washington State 45-42 Saturday afternoon at Arizona Stadium.

Randall threw two second half touchdowns, one to Cayleb Jones and another to Johnny Jackson, but the Wildcats couldn't overcome a Cougar offense that accounted for 631 yards of total offense and six touchdowns.

Washington State quarterback Luke Falk completed 47 of 62 passes for 514 yards and five touchdowns. By halftime, Falk had 335 yards and four scores.

Falk and the Cougars scored on their first drive of the game, marching 78 yards on 10 plays over 4 minutes and 32 seconds. The quarterback found Gabe Marks for a 6-yard score to give Washington State an early 7-0 lead.

The Wildcats (5-3, 2-3 Pac-12) punted on their first two drives and the Cougars took over with 3:55 left in the opening quarter. This time, Falk and the Cougars (5-2, 3-1) needed just four plays to march 80 yards with the quarterback again hooking up with Marks for a touchdown. This time, Falk found Marks for a 43-yard score to make it 14-0 late in the first quarter.

Arizona got on the scoreboard on its third possession of the game when the Wildcats went 75 yards on 13 plays and scored on a 1-yard run from senior running back Jared Baker.

The Wildcats defense forced another Washington State punt with just more than 12 minutes left in the half. Cougars punter Zach Charme punted to Arizona junior receiver Nate Phillips, who busted through the Washington State punt team to return it 69 yards for a touchdown to tie the game 14-14.

But the Cougars scored on their next four drives with three touchdowns and a field goal. The first score of the bunch again came from Falk and Marks. The two finished off a nine-play, 78-yard drive with a 2-yard touchdown pass to make it 21-14.

Arizona fumbled the ensuing kickoff, giving Washington State the ball at the 23-yard line. Washington State needed just four plays to reach the end zone when Falk found Kyrin Priester for a 6-yard touchdown to make it 28-14 with 6:51 to play in the half.

Baker cut it to a seven-point game when he scored from seven yards out with 4:22 to play in the first. But Washington State's Erik Powell connected on a 25-yard field goal with 24 seconds left in the half to extend the lead to 10 points.

After a Homecoming halftime that honored former Arizona greats Ka'Deem Carey and Bobby Wade, the Cougars again stretched their lead to 17 on their first possession of the second half. Gerard Wicks capped an 84-yard drive with a 1-yard score to make it 38-21.

Arizona coach Rich Rodriguez then opted to bring Randall into the game for starter Anu Solomon. For the second straight week, Solomon was productive, passing for 145 yards and rushing for 24 on three carries. But looking for a spark, the Arizona coach turned to Randall.

The senior from Hollywood, Florida provided it, coming through with a 59-yard rush on his first possession. On his second, after a Washington State punt, he drove Arizona 80 yards on 11 plays and found Cayleb Jones for a 3-yard touchdown to make it 38-28.

The Wildcats got the ball back with the score the same and Randall again drove Arizona deep into Washington State territory. Baker scored from six yards out to cut it to 38-35. It was Baker's third rushing touchdown of the game.

But Falk and Marks connected one final time to put the game out of reach when Marks hauled in a 9-yard touchdown from Falk with 2:03 left in the game.

Randall found Johnny Jackson for a 20-yard touchdown with 44 seconds left, but Arizona was unable to pounce on an onside kick, giving the ball back to Washington State.

Randall finished 11 for 16 for 137 yards and two touchdowns and added 105 rushing yards on just 10 carries. He played the remainder of the game after taking over for Solomon.

“He did a great job,” receiver Cayleb Jones said of Randall. “His number was called late, and he was ready. The guys behind No. 1 have to be ready and Jerrard did a great job.”

Jones finished with a season-high 131 yards on eight catches for his sixth career 100-yard game. The junior also threw a 25-yard pass to Trey Griffey on a trick play.

Defensively for Arizona, Paul Magloire led the way with 11 tackles, including one for a loss. Jeff Worthy also had a strong game, compiling five tackles, 2.5 tackles-for-loss and 1.5 sacks.

The Wildcats will look to bounce back next week at Washington. The Halloween game is set for 8 p.m. MST.
