SALT LAKE CITY -- Give those Harvard kids an A-plus in another subject: Bracketbusting 101.

The school known for producing U.S. presidents, Supreme Court justices and Nobel Prize winners earned its first NCAA tournament victory Thursday night -- a 68-62 upset of No. 3 seed New Mexico -- and it didn't feel like a fluke.

Wesley Saunders scored 18 points and Laurent Rivard made five 3-pointers to help the 14th-seeded Crimson pull the biggest surprise of March Madness so far.

Reaction came quickly, and from various corners.

"America, we are sorry for messing up your brackets and also your financial system and everything else," tweeted the jokesters at the Harvard Lampoon.

And this from Harvard's most famous hoops alum, Jeremy Lin: "YYYYYEEEEESSSSSSSSS!!! HARVARD winssss!!! hahahahhah i told you," he tweeted shortly after the victory.

Everybody ready for Crimsonsanity?

Next up for Harvard (20-9) is a meeting with sixth-seeded Arizona, which beat Belmont 81-64 earlier in the West Region.

"This is the No. 1 moment in my career," said Harvard senior Christian Webster, who finished with 11 points. "The thought came to mind that this could be the last game. We showed a lot of toughness, just persevering."

Indeed.

The Ivy Leaguers put the clamps down on New Mexico's Tony Snell, holding him to nine points on 4-for-12 shooting after he dominated in the Mountain West Conference tournament. They banged inside with Lobos big men Cameron Bairstow and Alex Kirk, whose 22 points provided New Mexico's only consistent offense.

Mostly, they showed none of the jitters that marked their trip to the tournament last year, a 79-70 loss to Vanderbilt in the Crimson's first NCAA appearance since 1946.

Rivard went 6-of-7 from 3 in that one -- played on New Mexico's home court in The Pit -- and was clearly pumped for an encore against the Lobos themselves. He was 5-of-9 this time, with three of them coming in the first half, while Harvard was holding a small lead and, more importantly, answering every surge the Lobos (29-6) could muster. Rivard finished with 17 points.

"I hit my first one, and you know, you hit the shot and then you keep shooting after that, and then I hit another one, so I knew it was going to be a good game after that," Rivard said.

Coach Tommy Amaker called Rivard the best 3-point shooter in Boston this side of former Celtic Ray Allen.
