INDIANAPOLIS — Chris Duarte scored 23 points and Oregon showed no signs of rust after a long layoff, beating No. 2 seed Iowa 95-80 on Monday to reach the Sweet 16 for the fourth time in the past five NCAA Tournaments.

The seventh-seed Ducks (21-6) were put in an unprecedented spot, advancing to the West Region's second round without playing a game. Virginia Commonwealth's multiple positive COVID-19 tests took care of that, leaving Oregon with a nine-day break since losing in the Pac-12 Tournament title game.

Oregon's offense hummed like it was fresh off the line once the ball went up, kicking off the NCAA Tournament's first Monday of second-round games with a masterpiece.

The Ducks flowed on the floor and glowed on the scoresheet, shooting 56% and hitting 11 3-pointers. LJ Figueroa hit five 3s while scoring 21 points and Will Richardson added 19 points in an offensive domination.

Their sweet offensive movements left the Hawkeyes (22-9) flailing, one game short of the Sweet 16 for the fourth time under Fran McCaffrey.
