The win kept ISU's hopes of qualifying for the Big Sky post-season tournament alive.

Idaho State (13-13, 4-9 Big Sky) opened the game with consecutive 3-pointers by Schroeder and Akbar Abdul-Ahad for a 6-0 lead.

Weber State (10-17, 4-10 Big Sky) made only three of its first 17 shots as ISU opened up a lead as large as 11 points midway through the half.

Weber State guard Terrell Stovall single-handedly led the Wildcats back into the game, scoring 15 straight WSU points during a 17-3 run to give Weber State a 39-30 halftime lead.

Idaho State chipped away in the second half, finally regaining the lead at 57-55 on two Tim Henry free throws with 12:41 left.

The game was back and forth until two more free throws by Henry gave ISU a six-point cushion with 1:58 to play.

Henry finished with 18 points for Idaho State. Stovall had a career-high 27 points for Weber State, while Coric Riggs added 17 points and David Patten came off the bench to add 12 points and a team-high nine rebounds.

Stuckey hit 3 of 4 from the foul line in the final 25 seconds as the Eagles (15-14) advanced to a conference semifinal matchup against Montana in Flagstaff, Ariz., on Tuesday. Tournament host Northern Arizona meets Sacramento State in the other semi.

Portland State finished 12-17.

Eastern, which led by 14 at halftime, saw its lead dwindle to four, 68-64, on a three-point play by Anthony Washington with 4:13 to play. A 3-pointer from Stuckey put EWU back up by eight, 73-65, with 2:45 left.

After a Stuckey free throw made it 77-72 with 25.1 seconds left, Portland State's Juma Kamara buried a deep 3-pointer to pull the Vikings to within two points, 77-75. Stuckey and Matt Penoncello each hit two foul shots to seal Eastern's win.

Stuckey, named the league's MVP earlier this week, hit 13 of 20 from the floor and had four 3-pointers as he led EWU in scoring for the 25th straight game. Paul Butorac chipped in 13 points and five rebounds and Deuce Smith six rebounds and six assists for the Eagles, who shot 64 percent from the floor.

Washington finished with 18 points, hitting 7 of 7 from the floor, for PSU. Kamara added 16 points and Jake Schroeder 12 for the Vikings. PSU, which had four straight wins, played without center Scott Morrison, suspended for a game after last weekend's win over Montana.

Montana, the defending Big Sky tourney champion, blew a 13-point lead in the final 8:30. The second-seeded Grizzlies (22-6) on Wednesday night will meet the winner of the other semifinal between top-seeded Northern Arizona, the tourney host, and No. 5 seed Sacramento State. The Grizzlies are one win away from reaching the NCAA tournament for the third time since 2002.

Rodney Stuckey, the Big Sky's Most Valuable Player, led Eastern Washington (15-15) with 26 points. He hit two free throws with 20 seconds left to force overtime.

Leading 55-42 with 8:30 to play, Montana appeared to be in control. But the Eagles went on a 10-0 run. Stuckey was a key player in the rally, scoring four straight baskets in one stretch as the Eagles chipped away at the deficit.

With 1:55 to go, Stuckey scored on a lay-up and was fouled by Criswell. Stuckey missed the free throw but grabbed the rebound and fed Paul Butorac for the lay-up that tied the score at 59-59.

Montana's Virgil Matthews scored on an inbounds pass to put the Grizzlies up 61-59. After an Eastern Washington turnover, Criswell went up for what appeared to be the game-clinching shot. But it was blocked and Stuckey drew an intentional foul on Matthews with 20 seconds left. Stuckey hit both free throws.

On the ensuing possession, Stuckey dribbled the down game clock before missed a leaning 10-footer at the horn.

Stuckey scored the first basket of overtime to put Eastern Washington up by two, but he later had a shot blocked, leading to a fast break lay-up, and committed a turnover. The Grizzlies clinched it by scoring six straight points after Eastern Washington took a 65-63 lead. Montana limited the Eagles to one field goal in the first four minutes of overtime.

Criswell scored six of Montana's 12 points in overtime. He hit four straight free throws in the final 18 seconds to seal the victory.

Smith scored all 11 of his points in the final 10 minutes, including two crucial free throws with 25 seconds left that gave CSU a 63-60 lead.

TCU's Brent Hackett misfired a 3-pointer, and Cory Lewis iced it with a free throw with 11 seconds left.

Freddy Robinson's 16 points led the Rams (16-14), who will face league champion San Diego State (21-8) in the quarterfinals Thursday at the Pepsi Center.

The Horned Frogs, who got a season-best 28 points from Nile Murry, finished 6-25.

Smith, the Rams' leading scorer with a 16.5-point average, didn't score until 9:56 was left when his short jumper gave CSU a 49-45 lead.

From then on, it was Smith vs. Murry.

Murry's driving layup and 3-pointer tied it at 55 with 4:47 remaining, but Smith replied with a 17-foot swish shot to give the Rams a 57-55 lead. Smith missed two free throws, and Murry sank both of his foul shots at the other end to tie it at 57 with 3 1/2 minutes remaining.

Smith, who was 4-of-10 from the floor and 3-of-7 from the line, missed a baseline drive to the basket but muscled his way for the board and his putback gave the Rams a 60-58 lead at the 2-minute mark.

Murry responded with a nifty reverse layup in traffic to tie it once again.

After a Rams' turnover, Judson Stubbs, who scored 12 points, misfired a short shot and compounded it by fouling out when he hammered CSU's Michael Harrison while trying to grab the rebound. Harrison missed his first shot but sank his second to give the Rams a 61-60 lead with 1:08 left.

Murry's runner from the right side banged off the rim with 38 seconds left, and Smith grabbed his eighth rebound. After a timeout, Smith drew the foul on the inbounds and sank both his free throws for a 63-60 lead.

Northern Arizona (21-9) advanced to Wednesday night's final, where the Lumberjacks will meet second-seeded Montana, a 73-71 overtime winner over third-seeded Eastern Washington in the other semifinal. NAU has won 11 straight at home.

Loren Leath came off the bench to lead the Hornets (15-15) with 20 points.

The Lumberjacks are one win away from their third NCAA tournament berth and their first in six seasons. Even if they lose the conference final, the Lumberjacks are guaranteed an NIT berth as a regular-season conference champion.

NAU didn't know what to expect as it took the floor for the first time in nine days. The Lumberjacks had finished the regular season with double-digit road losses to Western Kentucky and Montana wrapped around a victory at Sacramento State.

By winning the regular-season title, NAU earned the right to host the final two rounds of the Big Sky tournament. The Lumberjacks had hoped that playing at 7,000 feet would work to their advantage.

The thin air didn't bother the Hornets early in the game. They hit five of their first six shots on their way to a 15-7 lead after five minutes.

But NAU went on a 16-4 run to take a 28-23 lead midway through the half. The big shots came from Sir, who hit a three-pointer and a baseline jumper and added a pair of free throws. Sir, the nation's most accurate three-point shooter at 49.7 percent, hit 5-of-7 three-pointers.

NAU turned up the defensive pressure midway through the half, limiting the Hornets to one field goal in a nine-minute span. A 19-5 spurt over the final seven minutes gave the Lumberjacks a 49-34 halftime lead.

At intermission, Sacramento State had more personal fouls (14) than field goals (11) and was outrebounded 25-10.

The Hornets opened the second half by hitting four of their first six field goals. But Bazy, a slashing 6-foot guard, scored four consecutive baskets to help NAU maintain a comfortable lead.

Sacramento State used a 12-2 run to pull within 80-76 with 5:30 to play only to see Sir and Ruben Boykin Jr. have three-point plays to put NAU up 86-76.

Jeff Graham had tied the score with four seconds left with two free throws for Western (13-18).

Northern (19-12) inbounded the ball and Jordan Matthews connected with Wilson on a halfcourt pass that Wilson put through the hoop for the winning score.

Matthews finished with 15 points to lead the Lights. Wilson added 14 points, followed by Reid Stovall with 13 and Brian Erickson with 11.

Northern will play fourth-ranked Carroll (26-3) in a semifinal game Friday at 4 p.m.

Wes Morales led Western with 19 points, followed by Charlie Cox with 16 and Graham with 11.

The Lights led 35-31 at halftime.
