North Carolina and Vanderbilt were cruising along in the NCAA baseball tournament, looking every bit like the top two national seeds.
Now, they're suddenly facing elimination.
North Carolina, No. 1 overall, was stunned by Florida Atlantic 3-2 on Sunday night when Ricky Santiago hit a three-run homer in the seventh inning. The teams meet Monday night to determine the regional title.
"This club has pretty much led themselves all year," UNC coach Mike Fox said. "I trust my team. We've got some good leaders in there. I'm sure they're not very happy. We do have another game to play, so it'll be up to them and us and everybody to shake this one off and come into the ballpark tomorrow and be ready to play."
Santiago's homer was the first hit for the second-seeded Owls (42-21) and one of three all night. But the Tar Heels (54-9), while managing 12 hits, left 15 runners on base and repeatedly came up empty in key moments.
The Tar Heels, who started 39-2 and won the Atlantic Coast Conference title, must pick themselves up from a regional loss that looked similar to last year's loss to St. John's on a walkoff homer.
UNC hasn't lost consecutive games all season.
Florida Atlantic beat Towson 6-5 in an elimination game earlier Sunday.
In the Nashville regional, Josh Heddinger pitched a two-hitter and Georgia Tech beat No. 2 overall seed Vanderbilt 5-0 to force a rematch Monday for the Nashville regional title.
The Yellow Jackets pulled away with three runs in the sixth, including a two-run home run by Mitch Earnest. Georgia Tech (37-26) has won three straight — including beating Illinois 6-3 earlier in an elimination game — after losing its NCAA tournament opener.
The Commodores (53-10) were shut out for just the second time this season.
Oregon, the No. 8 national seed, staved off elimination by winning twice Sunday, beating San Francisco 6-1 and Rice 11-0. Oregon and Rice will meet again Monday, with the winner advancing to the super regionals.
Four national seeds — No. 3 Oregon State, No. 4 LSU, No. 6 Virginia and No. 7 Florida State — all advanced with regional-clinching victories.
Cal State Fullerton, the No. 5 national seed, advanced to a super regional matchup against UCLA after beating Arizona State 6-1 late Sunday.

Healy went 4 for 4 with four RBIs and two runs for the Ducks (48-15), who got eight extra-base hits off a combined five Rice pitchers.
Oregon kept its season alive earlier by beating San Francisco as Tyler Baumgartner hit a home run and scored three runs to back freshman pitcher Cole Irvin's sensational postseason debut.

Derek Fisher emerged from an NCAA tournament slump with two hits and three RBIs and Virginia advanced to the super regionals for the fourth time in five years with an 11-3 victory against Elon.

Ethan McKinzie threw a four-hitter in just his third start of the season to lead Central Arkansas over Mississippi State for a 5-2 victory.
Central Arkansas (42-21) forced a winner-take-all rematch Monday for the Starkville regional title.
Mississippi State (45-18) tied the game 2-2 in the sixth on Sam Frost's run-scoring single, but Central Arkansas responded with three runs in the bottom of the inning.

Thomas Eshelman pitched eight dominant innings and Cal State Fullerton advanced to the super regional with a 6-1 victory over Arizona State.
The Titans (51-8) will host UCLA in their first super regional appearance since 2010, when they also faced UCLA.
Eshelman (12-2) was the second Titans freshman right-hander to shut down the Sun Devils (37-22-1) in as many nights after Justin Garza threw 8 1-3 shutout innings in Fullerton's 1-0 win over ASU on Saturday.
The Titans scored five times in the first two innings against ASU left-hander Adam McCreery (2-4), who walked six of the 12 batters he faced and hit another and was pulled after only 1 1-3 innings.
