Check back throughout the night for more insights on the latest results.

Marquette vs. UConn

Entering the day, UConn held the final 1-seed in bracketology, with Florida continuing to close the gap and erase a head-to-head deficit. Marquette, unless they can make a run to the Big East title next week, played for nothing but the right to ruin the Huskies’ day.

The Big East standings also see plenty on the line, with St. John’s locking up at least a share of the regular season title on Friday night. UConn needed the win to join them, while Marquette is locked into a first-round matchup.

Marquette trailed at halftime, but was able to stretch out a second-half lead and upset UConn. The Golden Eagles can now carry that momentum into a Big East Tournament which has seen miraculous runs many times before.

For UConn, the result could prove devastating to their resume, adding a Q2 loss to their resume which will be closely compared to Florida in the next week. They will likely lose the 1-seed spot in Sunday’s bracketology update, needing a Gators loss between now and Selection Sunday to get back on top.

Kentucky vs. Florida

Entering the weekend, Florida sat on the 2-seed line of bracketology, just behind UConn which held a head-to-head result to overrule the analytic advantages that the Gators created in recent weeks. Meanwhile, Kentucky sat on the cusp of the 7-seed and 8-seed conversation, getting the nod for the higher of the two.

The defending champions already secured the SEC regular season title and a 1-seed in the SEC Tournament with their midweek win, so they did not have any chance for movement in the conference standings. However, Kentucky needed a win to capitalize on the earlier Vanderbilt win over Tennessee and jump in the seeding for next week.

Florida was able to pull away and hold onto the lead after a second half comeback, further strengthening their 1-seed resume as they look to make a leap over UConn. The Huskies loss opened the door and the Gators burst through it with this result.

Kentucky will benefit from other results around them in the bracket, despite the big loss. The Wildcats are likely to fall just one spot, but will end up on the 8-seed line as Georgia holds a head-to-head advantage with similar analytic numbers.

Bubble movement

The NCAA Tournament bubble continues to shrink with just one week left in the regular season, as more teams can consider themselves safely in the mix. However, there are two or three spots left to battle for above the cutline.

• Virginia Tech could fall out of the mix for an at-large spot, with ground to make up against the cutline in ACC Tournament play. They do get favorable results elsewhere, which have left the door cracked open.
• Missouri missed a chance to leave no doubt entering the SEC Tournament, with a loss against Arkansas leaving them on the right side but in need of a postseason win or two to breathe easy.
• TCU is locked into the NCAA Tournament field with a win over Cincinnati, while the Bearcats leave a lot of work for the Big 12 Tournament as they drop below other bubble candidates.
• SMU leaves itself in serious danger with a four-game losing streak to close the regular season, keeping their spot in the Last Four In in jeopardy before conference tournaments start.
• Stanford refuses to leave the bubble conversation all-together, picking up another Q1 win against NC State which brings their total up to five, despite three Q3 losses.
• New Mexico joins the group of bubble teams which take a loss, falling against Utah State in a result which will leave them more to do in the MWC Tournament next week.
• California takes a loss against Wake Forest which pushes them far enough down the board of bubble contenders that an at-large berth is likely ruled out.
• Ohio State should be able to lock itself into the field with a season-ending win over Indiana. One the other side, the Hoosiers fall onto the wrong side of the cutline entering the conference tournament.
