CORVALLIS — The third quarter was South Albany High’s downfall Thursday night in an OSAA 5A quarterfinal loss to Crater.

The Rebels were tied at the half against the No. 2-seeded Comets before being outscored by 10 in 65-54 loss that dropped South into the consolation bracket.

But on Thursday morning, it was the Rebels who used a third-quarter advantage to take control.

No. 7 South Albany outscored No. 6 Mountain View 15-9 in the third and then pulled away down the stretch to come away with a 72-60 victory at Gill Coliseum.

South (21-6) will play Mid-Willamette Conference rival and No. 1 seed Silverton at 10:45 a.m. Friday for fourth place. The Rebels lost both meetings this season (69-42 at Silverton and 82-57 at home).

The Rebels went 0-2 at the state tournament last season, falling to No. 1 Wilsonville and No. 4 Summit last year.

Seth Cullison scored a game-high 23 points with Jake Costello adding 22 for the Rebels.

Ian Amoroso had 14 for Mountain View while Matt Van Tassell added 13 and Sawyer DeMeyer 10.

Like Thursday’s quarterfinal with Crater, the Rebels went to the half tied at 30.

And while the third quarter may not have started off great Thursday — the Cougars took a 34-30 lead on a four-point play — the Rebels responded with a 10-0 run, capped off by Ivan Rodriguez’s layup with 4:11 to play, for a 40-34 lead.

Four different players scored in the run.

The Cougars, however, responded with five straight before Costello drained a 3 to put the Rebels back up four at 43-39 with 2:27 left in the quarter.

Two Costello free throws gave the Rebels a 45-39 lead heading to the fourth.

Mountain View cut the deficit to four twice but the Rebels were able to pull away by converting from the free-throw line. South was 17 for 26 from the line in the fourth and 27 for 42 for the game.

South trailed 13-11 after one and used an 11-4 run to take a 22-17 lead and led 26-20 with 3:26 left in the half.

But Mountain View countered with an 8-1 run to take a 28-27 lead. The teams traded baskets before Jaden Guilford hit one of two free throws to tie with 4 seconds left in the half.

South was 9 for 24 from the floor, including 5 for 14 from beyond the arc.

Costello and Cullison had eight each for the Rebels.

Mountain View finished the half 10 for 24 from the floor (5 for 11 from 3) and was 5 for 6 from the line.

South fell behind 6-0 two minutes into the game but then scored nine straight, the run capped by Cullison’s 3.

South held the Cougars scoreless for 4 minutes, 14 seconds before DeMeyer’s 3 tied the game at 9-all.

DeMeyer scored seven points as the Cougars took a 13-11 lead into the second.
