Xavier got a little too high over its win over Villanova earlier this week, and ran into a team that needed and wanted it more in Seton Hall on Sunday.
The result was a 90-81 win for the Pirates, which really helped their tournament resume.
The news isn't so good for the Musketeers, who fell from the top line of the bracket.
Michigan State has moved up to take Xavier's place as a No. 1 seed on the latest bracket update.
The Spartans have certainly had the look of a No. 1 seed for about a month, and they have built a profile to back it up. Michigan State has won eight of its last nine, with the only loss coming in overtime at Purdue.
Other notable results from early Sunday and their impact on this bracket update:
- Pitt finally got the signature win it has been lacking this season with a 76-62 win at home over Duke. That is just the second top 50 win for the Panthers, joining a road win over Notre Dame earlier this season. That's a big addition to the Panthers' tournament profile.
- UConn's 75-68 home loss to Houston cost the Huskies two spots as they fell from a No. 8 to a No. 10 seed and dropped them to sixth place in the American Athletic Conference. The thing keeping them down in the bracket is their inability to play well against the better teams in the league. They are currently 3-6 against the top five teams in the league. The problem is, one of those isn't an at-large team and three others are on the bubble with them.
- Saint Joseph's had no trouble with Saint Louis in a 77-63 win. That's what you would expect from a team trying to play its way up the bracket. Saint Joseph's can now focus on a trip to St. Bonaventure, another team on the bubble.
The bracket will be updated again at the end of Sunday's action.
