The Trojans couldn't do a lot of things Saturday in Eugene, Ore.
They couldn't convert free throws or three-point shots. They couldn't handle playing at McArthur Court, drawing a Class A technical foul at a key point in the second half.
And they definitely couldn't stop Jeremy Jacob — or Malcolm Armstead, for that matter.
USC (12-9, 4-5) held Oregon's Tajuan Porter and Michael Dunigan to a combined 11 points, but the Ducks' Jacob put up a career-high 19 points and Armstead had 18.
The Trojans got 16 points from Dwight Lewis and 12 from Mike Gerrity, but some of the usual contributors were unusually silent. Forward Marcus Johnson played nearly the whole game and scored only five points. Forward Alex Stepheson started and was held scoreless.
Oregon (12-9, 4-5) matched USC's record with the win. The Ducks had been hurting of late, losing their last five before this weekend, but visits from UCLA and USC proved to be just the right formula to snap out of it.
An 8-2 start to the game — capped by a signature Porter three-pointer — forced USC coach Kevin O'Neill to call an early timeout. The Trojans recovered, though, taking the lead at 17-15 on a Lewis three-pointer.
The game was close into the second half, with the score tied 47-47 with less than six minutes left. But from there, the Ducks used a Porter jumper and eight consecutive free throws to take a 57-47 lead. USC wouldn't be able to bring the game back into reach.
Altogether, the Trojans made only five of 11 free-throw attempts, compared to 15 of 19 for Oregon. The Ducks made six of 12 three-pointers and USC made six of 18.
With the loss, USC fell to 1-6 on the road this season — with the one victory coming 15 miles away in Westwood. The loss also ended the Trojans' four-game winning streak at McArthur Court.
Up next for USC is a Thursday night game against Pac-10 frontrunner California at the Galen Center. The Bears (14-6, 6-2) beat Arizona State, 78-70, on Thursday and play Arizona on Sunday.
