Tony Woods scored a career-high 17 points as Oregon remained undefeated with a 67-45 victory over Jacksonville State on Monday night.E.J. Singler added 11 points and Dominic Artis had 10 for the Ducks (4-0), who are off to their best start since also going 4-0 in 2007-08 - the last season they went to the NCAA tournament."At times I thought we played pretty well," Oregon coach Dana Altman said. "Tony did some good things protecting the basket and using some offensive moves."Woods, a 6-foot-11 senior center, was 8 for 12 from the field and also tied his career high with five blocks.He scored the first four points of the game on put-backs, setting the tone early for what would be a long night inside for the undersized Gamecocks."It was a big game," Woods said. "They lacked size inside tonight and I was able to take advantage of that and have a big game."Chris Deanes had 10 points to lead the Gamecocks (3-2), who have dropped consecutive games after opening the season with three straight wins for their best start in 18 seasons.And much like their 77-58 loss to No. 18 UNLV last Saturday, this one wasn't close.Oregon led 37-20 at halftime. Woods had 12 points and four blocks in the first half, and Singler had 11 points with three 3-pointers.The Gamecocks never got closer than 17 points in the second half.Oregon outscored Jacksonville State 34-24 in the paint and 18-8 on second-chance points, a product of the Ducks' 37-26 advantage in rebounding.Oregon also had 27 points off the Gamecocks' 23 turnovers.Overall, the Ducks shot 47.4 percent from the field after making 50 percent in the first half.The Ducks will put their hot start to the test later this week when they play UNLV on Friday and either No. 22 Cincinnati or Iowa State on Saturday at the Global Sports Classic in Las Vegas."We've still got a lot of work to do, especially this coming week," Singler said. "It's a big challenge ahead."
