MOSCOW — Brett Smith’s fifth touchdown pass of the game, a 25-yarder to Jalen Claiborne in overtime, lifted Wyoming past Idaho 40-37 on Saturday.

Idaho (0-4) had tied the game on the final play of regulation, when quarterback Dominique Blackman tossed an 8-yard pass to Mike Scott in the corner of the end zone. Trey Farquahar’s extra point made it 34-34.

Farquahar’s 49-yard field goal put the Vandals ahead in overtime, but Smith and Claiborne pulled it out for the Cowboys (1-3).

Smith was 23-of-35 for 365 yards and was not intercepted, and Chris McNeill caught eight passes for 219 yards. Blackman finished 34-of-46 for 306 yards and had three touchdowns and no interceptions.

Ryan Bass ran 19 times for 121 yards for Idaho, and when Blackman found Najee Lovett for a 19-yard score, the Vandals led 27-20 with 4:51 left in the third quarter.

Blackman tried to score in the fourth quarter when he stretched the ball over the goal line only to have it pop loose. Smith responded with an 80-yard pass to McNeill that set up a Wyoming TD.

“It’s more painful,” Idaho coach Robb Akey said. “We’re talking about inches. Literally inches. You can pick your opportunity. It’s not just the last play of the game.”

Idaho finished with 506 yards of total offense — its most since October 2010.

“We’re getting ourselves closer,’’ Akey said. “We’re inches away, but that’s not good enough either.’’
