BOULDER, Colo. - Back when he was attending Loyola High School in Los Angeles, Jared Baker was a bona fide track star, shining in the premier sprinting events.

So on Saturday, when quarterback Jerrard Randall and the Arizona Wildcats turned their road game at Colorado into a fourth-quarter track meet, Baker felt right at home.

The redshirt senior running back rushed for 207 yards and two touchdowns on 23 carries and Randall added 81 yards on 11 carries as the visiting Wildcats ran past the Buffaloes in a 38-31 victory.

Baker and Randall combined for 148 yards and three touchdowns in the final quarter to lock up the win for the Wildcats, now winners of two straight.

Randall, a senior from Hollywood, Florida, entered the game near the end of the third quarter with the Wildcats trailing 24-17 and instantly brought momentum to Arizona's side. Sophomore Anu Solomon started for the Wildcats and was effective, throwing for 283 yards. But with Colorado showing a defensive alignment that allowed some room to run, coach Rich Rodriguez opted to bring Randall in and show a change of pace.

“Number eight came in and gave us a little lift,” Rodriguez said of Randall in his postgame radio interview. “The way they were playing us, we thought Jerrard would have some opportunities to get some runs and open our run game up.”

The coach was spot-on.

On his first drive, Randall moved the Wildcats 97 yards in just 90 seconds. Baker scored on a 45-yard rush on Arizona's sixth play of the drive to tie the game at 24. Randall had rushes of 15, 18 and 12 on that drive before Baker's touchdown.

The Arizona defense then forced Colorado to punt, giving the ball right back to Randall and the Wildcats.

Randall again found chunks of yards on the ground and hooked up with Cayleb Jones for a 31-yard pass, getting Arizona down to the 25-yard line. But after gaining seven yards, Randall was taken down hard and was forced to head to the sideline.

Solomon came back in and immediately threw a 25-yard touchdown pass to Baker on a wheel route to give the Wildcats the lead.

“Twelve came back in and didn't hang his head,” Rodriguez said of Solomon, who completed 22 of 37 passes and threw touchdown passes to Baker and tight end Josh Kern.

Leading 31-24, Arizona's defense again stopped Colorado, setting up the Wildcats at the Buffaloes' 35-yard line. Randall re-entered and he and Baker touched the ball the next seven plays with the quarterback pounding it in from one yard out to give Arizona a 14-point lead with just less than five minutes to play.

“The O-line was blocking so well tonight, things were just opening up,” Baker said.

Baker's 207 yards, a new career high, came one week after the senior ran for 123 yards on 10 carries against Oregon State. He's averaging 10 yards per carry over the past two games and filled in admirably for starter Nick Wilson, who missed the game with an injury.

“Jared ran well,” Rodriguez said. “Jared is a fast guy. When you give him a little bit of crease, he's able to take advantage of it.”

Randall has played in each of the last six games for the Wildcats and now has 534 rushing yards and five touchdowns on the season, showcasing his speed.

The Wildcats improved to 5-2 on the season and 2-2 in Pac-12 play with the win. Arizona will return home next weekend to host Washington State at 1 p.m. for Homecoming. The game will be televised by Pac-12 Networks.
