TAMPA, Fla. — Privately, some Siena players wondered in recent days if their counterparts on the Vanderbilt roster knew any of their names.

If the Commodores didn't, they surely do now.

Kenny Hasbrouck and Tay Fisher personally saw to that, and the Saints have another colossal upset to add to their tiny school's NCAA tournament legacy.

Hasbrouck scored 30 points, Fisher added 19 on 6-for-6 shooting from 3-point range, and 13th-seeded Siena stunned No. 4 Vanderbilt 83-62 tonight in the first round of the Midwest Regional. The Saints (23-10) never trailed, became the first Metro Atlantic Athletic Conference team to reach the second round since Manhattan in 2004, and will play either Villanova or Clemson on Sunday.

Until now, Siena's program was best-known for a first-round upset of Stanford in 1989 — a 14 seed over a 3. This one might have been just as shocking, considering it came against a Southeastern Conference team in Vanderbilt that reached the round of 16 last year and had aspirations of doing at least that much this year.

But this might not have been a surprise.

After all, it was in Tampa, which might now have a reputation as a bracket-busting sort of town. Earlier Friday, two other unheralded underdogs pulled off upsets on the same floor where Siena won: No. 12 Western Kentucky beat fifth-seeded Drake and No. 13 San Diego ousted fourth-seeded Connecticut.

A.J. Ogilvy scored 18 points for Vanderbilt (26-8), which got 13 from SEC player of the year Shan Foster — who became the 22nd player in SEC history to eclipse the 2,000-point career mark — and 10 from Ross Neltner. The Commodores came into the tournament more than a little miffed that they were widely picked to be a first-round upset victim and insisted they wouldn't look past Siena.

Vanderbilt simply couldn't stop Siena, either.

The Commodores got two straight baskets from Keegan Bell and drew within 50-43 with 13:20 to play, but never got any closer the rest of the way. Vanderbilt never got its perimeter game going, shooting 4-for-20 from 3-point range, and didn't exploit its size advantage inside.

When Alex Gordon airballed a 3-point try with 1:25 left and Vandy in a 19-point hole, the Commodores knew it was over and stopped fouling, allowing the Siena celebration to begin in earnest.

When it was over, Siena coach Fran McCaffery picked Fisher up in a hug, hoisted him in the air and held him there for several seconds. A team that was 6-24 three years ago when McCaffery arrived is now in the round of 32, a timetable that even the coach finds mildly surprising.

Foster didn't get his first shot until 15:55 remained in the first half, and by then, the Saints were already off and running.

Moore hit a 3-pointer and Franklin scored inside for a quick 15-6 Siena lead, prompting the green-and-gold-clad backers who made their way from New York's capital region to start roaring.

And then Fisher — who hit six 3-pointers in the MAAC championship game, which was Siena's ticket to the NCAAs — began coming up big.

The smallest player on either roster, generously listed at 5-foot-9 and 162 pounds, hit three straight 3s in a span of 3:45 to stretch Siena's edge to 26-13, and when he made free throw with 8:15 left in the half, the Saints had a 31-15 lead.

Vanderbilt kept finding ways to draw closer.

Siena kept finding ways to seem unfazed.

The Commodores peeled off five straight points to get their crowd into it; Hasbrouck silenced them with a three-point play. Neltner and Foster scored consecutive baskets; Hasbrouck answered with a 3-pointer, steal and dunk in a 13-second span. When Vanderbilt drew within nine on a pair of free throws by Ogilvy with 40 seconds left in the half, Siena answered yet again.

Naturally, it was Fisher. Siena's only senior hit his fourth 3-pointer of the half — on as many attempts — with six seconds left, and the Saints marched into intermission with a 46-34 lead.

The Saints came in oozing with confidence, in large part because they know the Commodores just aren't the same away from home.

On their own floor this season, Vanderbilt was 19-0, averaging 85.1 points and outscoring opponents by 11.7 per game. Away from home, Vandy dropped significantly in every department — a 7-7 record, a 74.4 scoring average and it was actually outscored by 1.2 points per outing.

The road jinx struck Vandy again Friday.

And now the Commodores are heading home for the season.
