In one of the biggest upsets in NCAA Tournament history, 15th seed Saint Peter's shocked second seed Kentucky 85-79 in overtime in their first-round East regional game at Gainbridge Fieldhouse in Indianapolis.

Daryl Banks III scored 27 points and Doug Edert added 20 as the Peacocks (20-11) became just the tenth 15 seed to defeat a 2 seed in tournament history. The win was the program's first in four tournament appearances.

"It was an amazing feeling", Banks said. "You grow up watching March Madness, the tournament, so to let that sink in ----- knowing the game was over, it felt really good."

"At the end of the day, every team that made the NCAA Tournament deserves to be here", said Peacocks head coach Shaheen Holloway. "Every team that made the NCAA Tournament believes they can advance. It's about this night."

Oscar Tshiebwe, the likely Naismith Player of the Year, scored 30 points and grabbed 16 rebounds for Kentucky (26-8). The Wildcats suffered their first-ever first round loss under coach John Calipari.
