LEXINGTON, Ky. -- Colorado State's Dorian Green scored a career-high 26 points Thursday, more than enough to push the eighth-seeded Rams to a 84-72 win over ninth-seeded Missouri in a second-round game of the NCAA Tournament's Midwest Region.
Green had 17 points at halftime, helping the Rams take a 47-38 lead at the break. Colorado State (26-8) jumped out to an early 15-5 edge, taking advantage of poor Missouri shooting while crashing the boards and eliminating second chances for the Tigers.
Colorado State made the most of its early possessions, shooting 15-for-26 from the floor in the first half and going a perfect 11-for-11 from the free-throw line.
Missouri (23-11) was outrebounded 17-7 in the first half, so its 15-of-30 half from the floor didn't do much to bring it closer to the Rams.
The Rams finished with a 46-21 rebounding advantage, led by Colton Iverson's 13 boards and Pierce Hornung's eight. Colorado State entered Thursday's game No. 1 in the country in rebounding margin. Missouri was No. 3, though advanced statistics much more heavily favored the Rams.
Ken Pomeroy of KenPom.com rated the Rams No. 1 in defensive rebounding percentage and No. 2 in offensive percentage, advanced metrics to measure the amount of rebounds grabbed per opportunity. In those same ratings, Missouri was No. 9 and No. 50.
Missouri couldn't provide a consistent offensive threat to mount any sort of run in the second half. The closest the Tigers got was seven points, when Phil Pressey hit a 3-pointer with 5:06 to play to make the score 72-65.
However, the Rams answered with nine straight points and held Missouri without a point for the next four minutes.
Pressey scored a team-high 20 points. Alex Oriakhi added 16 for the Tigers, and Jabari Brown had 14.
Colorado State will play top-seeded Louisville on Saturday for a trip to the Sweet 16. The Cardinals, who are the tournament's overall No. 1 seed, cruised to a 79-48 rout of North Carolina A&T on Thursday.
The Rams have only appeared in one Sweet 16 in school history, in 1969.
