Dorian Green scored 17 of his 26 points in the first half and eighth-seeded Colorado State used good shooting to run away from No. 9 Missouri 84-72 Thursday night in the NCAA tournament.
Green, who went scoreless with five turnovers in last year's second-round upset to Murray State, did much better this time as the Rams shot nearly 58 percent in the first half.
Minnesota transfer and Rams big man Colton Iverson outrebounded Missouri by himself through 27 minutes and finished with 13 boards.
First-year Rams coach Larry Eustachy earned the victory with his fourth tournament team, but the road gets tougher as they advance to face top-seeded Louisville in Saturday's third-round Midwest Regional game at Rupp Arena.
Phil Pressey's 20 points led the Tigers (23-11).
