1991 PBA Third Conference finals

Alaska Milk won their first PBA title after five years, winning their finals series against Ginebra San Miguel, 3 games to 1.

Wes Matthews banged in a triple that tied the count at 90-all with 18 seconds to go, Chito Loyzaga shoved Ginebra ahead, 92–91, with two free throws.

With the score at 103–101 in favor of Ginebra, following Leo Isaac's 20-footer from left quartercourt with 30 seconds to go, the next play turned out to be controversial, Jojo Lastimosa's attempt bounced high off the rim with Paul Alvarez tipping the ball in, referee Bay Ledesma nullified the basket and giving the Gins possession with time down to 15 seconds, Rudy Distrito knocked in two more charities for a 105–101 advantage for Ginebra.

[2] Alaska stormed ahead, 88–73 on a 14–3 run, the Milkmen open gaps as wide as 23 points, 107–84, halfway through the final period.

Dondon Ampalayo muffed in a finger roll and a three-pointer, allowing Sean Chambers to knock in a running bank shot for a 95–90 count for Alaska.
