Jayson Mendoza sank the marginal basket with four seconds to play and Marvin Yambao picked up his seventh steal with a second left to preserve the victory.
"Thank God he was not fouled," said UAP coach Alexis Gonzales referring to Mendozas winning play.
The Pelicans missed 14 of their 18 foul shots in the payoff period, including their last five trips from the line. They trailed 57-67 early in the fourth.
After Herbert Arellanos basket gave Recolletos an 80-76 lead, Mendoza lost the ball at the baseline and things started to look bleak for the Pelicans.
But Yambao stepped in the Recolletos way getting a steal and feeding Alexander Bognot for a breakaway slam.
In the other game, the University of Visayas outclassed San Beda College, 77-69.
