ANAHEIM, Calif. (AP) — Justin Bibbins scored 17 points, Nick Faust added 15, and third-seeded Long Beach State upset No. 2-seed UC Irvine 77-72 in the Big West Conference Tournament semifinals Friday night.

The 49ers (20-13) will face top-seeded Hawaii (26-5) in the championship game Saturday.

A.J. Spencer scored 13 points and Travis Hammonds had 11 to help Long Beach State hold off a late charge from the defending conference tournament champion Anteaters (25-9).

The 49ers surrendered a 13-point second half lead, but went back on top when Faust hit a 3 with 6:07 left and led rest of the way.

UC Irvine beat Long Beach State in both of the regular-season meetings, including a 90-67 victory when the teams last met Feb. 24.

Jaron Martin scored 21 points and 7-foot-6 center Mamadou Ndiaye had 16 points, 10 rebounds and three blocked shots to lead the Anteaters.

Long Beach State led 39-30 at halftime and extended it to 45-32 before UCI slowly crawled back into it. After minutes of back-and-forth, the Anteaters finally broke through with a 20-9 run that gave them a 62-61 lead with 6:48 to go. Martin scored 11 points - including three 3-pointers - to lead the spurt and Mike Best scored the go-ahead layup off a no-look pass from Ndiaye in the paint.

It didn't last for long. Faust put Long Beach State back in front with a 3-pointer on the next possession, and back-to-back jumpers by Spencer and Hammonds made it 70-64 49ers with 3:53 remaining.

A series of free throws cut UCI's deficit to 70-68 with two minutes left, but it couldn't get any closer. Luke Nelson missed a potential go-ahead 3 with 1:48 to go and, after a 49ers free throw, Alex Young missed a 3-pointer to tie with 1:07 left.

Faust made them pay for the missed opportunities, hitting a jumper from the right wing with 38 seconds left to make it 73-68 Long Beach State, and the 49ers sunk four of their final six free throws to ice it.
