La Salle leaned on rookie Jeron Teng and its defense late in the game to hold off Adamson, 56-52, and get back on track with a 3-3 card.
Teng led his team with 15 points, including a basket that gave the Archers the lead for good and a free throw that put away the Falcons.
La Salle coach Gee Abanilla said the injury to starting point guard LA Revilla, who tweaked an ankle in the first half, threw them off balanced.
“LA Revilla’s injury threw us off a bit, I hope it isn’t serious,” said Abanilla. “Good thing about it is that the rookies were given a chance to play and I think they perform really well.
“I hope they will perform better for us to do well in our future games,” he added.
Ryan Monteclaro led his team with 12 points but the Falcons missed main man Alex Nuyles, who will be out the rest of the season with a shoulder injury, that they couldn’t deliver when it mattered most. They fell to their fourth setback against a win.
Roider Cabrera gave Adamson a 52-51 lead with a little less than two minutes to go but the Falcons couldn’t score from there while Teng secured the victory with his clutch shooting.
