And then there were two.
The 11-seed UCLA Bruins went on a Cinderella story run and fought their hardest to keep it alive.
But they met their end against the undefeated, top-seeded Gonzaga Bulldogs, thanks to an unbelievable 3-pointer at the buzzer in overtime by freshman guard Jalen Suggs, propelling Gonzaga to a 93-90 win.
Before that, the 2-seed Houston Cougars faced the 1-seed Baylor Bears, as just one Texas team could two-step into Monday's national championship game.
That team was the Baylor Bears, who won in dominant fashion.
