JONESBORO, Ark. (AP) _ Greg Robertson threw three touchdown passes Saturday, including one in overtime that provided the winning margin in a 30-24 Big West Conference triumph over Arkansas State.

Idaho (4-2, 2-0 BWC) never trailed, but the game was tied at 14 in the second quarter and at 24 at the end of regulation time. The contest was decidedly different from last year's meeting of the two teams, won 52-14 by Idaho.

Arkansas State (1-6, 0-2) allowed the Vandals to take a 14-0 lead in the first period on Robertson scoring throws to Mike Roberg, from 4 yards out, and to Ethan Jones on a play that went 53 yards.

But the Indians came back to tie the game in the second period when Robert Kilow ran a punt back 75 yards for a touchdown, and Sean Mitchell picked up a fumble and made it to the end zone 34 yards away.

Idaho took a 17-14 lead into the locker room at the half after Ben Davis kicked a 23-yard field goal as time expired.

In the third quarter, the two teams traded TDS. Idaho's Anthony Tenner scored on a 31-yard run, while Lamont Zachery pulled in a pass from Andy Shatley and went 63 yards for an ASU score.

ASU's Nick Gatto tied the game with a 23-yard field goal early in the final period.

Robertson hit Roberg again in the end zone in overtime, from 2 yards out, to get the victory.

Idaho's Tenner and ASU's Zachery each rushed for 107 yards, Tenner on 18 carries, Zachery amassing his yardage on 20 rushes.

Robertson finished with 293 yards passing, completing 23 of 46 attempts and throwing one interception. ASU used three quarterbacks _ Cleo Lemon, Zachery and Andy Shatley _ who threw for 162 yards altogether, completing 12 of 27 throws with one interception, thrown by Lemon.
