I had to drive back from Richmond after the Colonial final Monday night, so this post will be really quick.

Four teams clinched NCAA bids on Monday night, with three teams getting themselves off the bubble in the process.

Colonial: Old Dominion held off William & Mary, 60-53. Read my recap over at SB Nation.

Metro Atlantic: For the third game in a row, Siena had to come back. They defeated Fairfield in overtime to claim the MAAC crown. (recap)

Southern: Wofford claimed the Southern Conference crown for the first time, thanks to a 56-51 win over Appalachian State. (recap)

West Coast: St. Mary's booked their place by pounding Gonzaga in the championship game in Las Vegas. (recap) The loss means the Bulldogs are likely to be shipped away from Spokane for the first weekend of the Tournament.

After the jump, I'll take a look at today's action, which features three championship games and the start of the Big East Tournament.

Sun Belt

The top two seeds will meet for the crown tonight (7, ESPN2). No. 1 Troy eliminated perennial power Western Kentucky, 54-48; while second-seeded North Texas topped sixth-seeded Denver, 63-56. The Mean Green won the only meeting between the two this season, claiming a three-point win in Troy.

Horizon

This one is another matchup of top seeds (9, ESPN). Top-seeded Butler hosts second-seeded Wright State in a rematch of the 2007 final. The Raiders won in '07 to make the Horizon a two-bid league. The Bulldogs won both meetings this year.

Summit

Three Tuesday finals, three 1 vs. 2 matchups (9, ESPN2), Top-seeded Oakland got a game from IPFW, but prevailed, 71-58. The Golden Grizzlies will take on No. 2 IUPUI, who won a close 69-65 contest against Oral Roberts. The two teams split their two meetings this season, with each winning at home.

Beyond those three finals, there is plenty of other conference tournament action on the schedule for Tuesday.

Atlantic 10

The A10 Tournament starts with four campus site first round games. The winners move on to Atlantic City for Friday's quarterfinals, where they'll meet the top four seeds -- Temple, Xavier, Richmond, and St. Louis.

(9) Duquesne at (8) St. Bonaventure, 7
(10) George Washington at (7) Dayton, 7
(11) Massachusetts at (6) Charlotte, 7
(12) St. Joseph's at (5) Rhode Island, 7 (Cox Sports)

Big East

The 16-team free-for-all opens in New York with four first round games, three of which have significant bubble importance. Today's winners move on to face seeds 5 through 8 Wednesday. For more information, check out SB Nation's preview.

(9) South Florida vs. (16) DePaul, 12 (ESPN2)
(12) Connecticut vs. (13) St. John's, 2:30 (ESPN2)
(10) Seton Hall vs. (15) Providence, 7 (ESPNU)
(11) Cincinnati vs. (14) Rutgers, 9:30 (ESPNU)

Big Sky

Action in this conference shifts to Ogden, Utah, where top-seeded Weber State is the host for the semifinals and final. They re-seeded the opening round winners, so the matchups are a bit non-traditional from a seeding perspective.

(2) Northern Colorado vs. (4) Montana, 6:35 (Altitude)
(1) Weber State vs. (6) Portland State, 9:05 (Altitude 2)

Mid-Eastern

The MEAC Tournament opens in Winston-Salem with two first-round games. The third takes place tomorrow.

(7) Bethune-Cookman vs. (10) Florida A&M, 6:30
(8) Howard vs. (9) North Carolina A&T, 9
