EUGENE — Joseph Young scored 28 of his career-high 36 points in the second half to help No. 18 Oregon rout Western Carolina 107-83 on Wednesday night.

Mike Moser added 26 points and Elgin Cook had 16 for the Ducks (2-0), who opened the season with an 82-75 win against Georgetown last Friday at Camp Humphreys, a U.S. Army base in Pyeongtaek, South Korea. They returned to Oregon the next day and resumed practice Monday.

Young, a transfer junior guard from Houston, made all seven of his shots in the second half and only missed three of his 12 attempts in the game. He was also 15-for-16 from the free-throw line.

Moser, a 6-8 transfer senior forward from UNLV where he was an All-American in 2012, scored 15 in the first half and went 9-for-14 from the field.

Trey Sumler scored 29 in his season debut for the Catamounts (2-1). The senior guard, who averaged a team-high 18.4 points last season and was an all-Southern Conference selection, missed the first two games of the season after being charged with assault and battery in September.

The Ducks (2-0) led 41-39 at halftime but then Young took over. He scored 17 points as Oregon extended its lead to 71-55 with 11:49 left.

Young and Moser hit back-to-back 3-pointers to open the second half and Oregon hit eight 3's in the game. The Ducks also went 35 for 47 from the free throw line.

Western Carolina cut their deficit to 73-67 with 9:08 to play on a 3-pointer by Sumler, his 13th straight point. But that was as close as the Catamounts would get, as Oregon outscored them 33-16 the rest of the way. Moser's 3-pointer with 11:57 to play in the first half put Oregon up 15-12 and came in the middle of a 14-1 run for the Ducks that turned a 12-8 deficit into a 22-13 lead. But just when it looked like the Ducks were primed to take a commanding lead, Brandon Boggs scored 10 straight for the Catamounts to pull them within a point of the lead, 37-36, with 1:42 to go before halftime.

Oregon State 79. Portland 73

At Corvallis, Roberto Nelson scored 24 points and tied a career high with seven assists as Oregon State beat Portland.

Angus Brandt added 13 points and 10 rebounds for the Beavers (1-1), and Devon Collier had 11 points and 11 rebounds.

Ryan Nicholas had 14 points and 13 rebounds for the Pilots (1-1), but shot 5 of 16 from the field. Bobby Sharp, a junior college transfer, came off the bench and added 18 points for Portland, making five 3-pointers.

The Beavers scored 11 straight points in the first half to take a 20-10 lead. Brandt had five points during the run.

Oregon State led 41-33 at halftime, but the Pilots tied the game 59-59 on a layup by Thomas van der Mars with 7:50 left.

The Beavers built a lead of seven points on a Nelson 3-pointer with 2:20 left and were able to hold off the visitors.

Oregon State lost 78-73 to Coppin State in its season opener at home on Sunday. Nelson led the Beavers in that game with a career-high 36 points. He has now scored in double digits in 19 straight games.

Collier started for the Beavers after serving out a suspension for a violation of team rules. He missed the team's two exhibition games and its season opener. The 6-foot-7 forward averaged 12.6 points and six rebounds last season.

Forward Eric Moreland did not play for the Beavers, suspended for the first 14 games of the regular season for a violation of team rules. Moreland finished second in the Pac-12 in rebounding, blocked shots and double-doubles last season.

Coach Craig Robinson has not elaborated on the reasons for Collier's and Moreland's suspensions.

Portland returns all five starters from last year, and six of their seven top scorers. Nicholas is the team's two-time leading scorer and rebounder.

Portland beat UC Davis 100-83 on Friday at home.

Oregon State plays at Maryland on Sunday. The two teams have never faced each other.

The Pilots face Michigan State on Monday.
