TUCSON, Ariz. — Through five games of his freshman campaign, Bear Bachmeier has been as-advertised for No. 18 BYU, a 68.7% passer with 1,048 yards and seven touchdowns, just one interception, and three Big 12 freshman of the week honors.

On Saturday night, the freshman was just that: a freshman.

Yet somehow the youngster overcame two interceptions, calling his own No. 47 jersey with a 2-yard touchdown run with 19 seconds remaining to force overtime after rallying from a 10-point fourth-quarter deficit.

With 2:55 remaining, Bachmeier directed an 11-play, 47-yard drive and — aided by a pair of pass interference penalties inside the 10 — forced overtime with his 17th carry of the night.

Noah Fifita threw for 219 yards and two touchdowns with an interception. But the redshirt-junior’s pass fell off the finger tips of Javin Whatley — with BYU’s Evan Johnson in coverage — as the Cougars survived, 33-27 at Arizona Stadium.

The comeback is what will be remembered, though.

Michael Salgado-Medina and Will Ferrin exchanged field goals in the first overtime, with Ferrin nailing a 45-yarder with ease to force a second extra period.

Bachmeier called his number again in the second overtime, diving in following a seven-yard run as the Cougars took a 33-27 lead.

LJ Martin ran for 162 yards and a touchdown for BYU (6-0, 3-0 Big 12), topping the 600-yard mark just one quarter into the sixth game of his third collegiate season.

Bachmeier finished with 172 passing yards and a touchdown, and ran for 89 yards on 22 carries. But his two interceptions must’ve felt like daggers as the Wildcats overturned a 14-0 first-quarter deficit with 24-0 run around an hour-long weather delay to start the second quarter as remnants of Hurricane Priscilla rolled through southern Arizona.

Will Ferrin connected on a 24-yard field goal with 4:08 remaining — his first make after three consecutive misses for the school’s record-holder for consecutive made tries — after Kedrick Reescano capped a 24-0 run with a 36-yard rushing score to put the Wildcats up, 24-14 to open the fourth quarter.

Reescano finished with a team-high 90 yards on 13 carries for Arizona (4-1, 2-2 Big 12).
