[1][2] Dubbed as "The Tank", He is best known for his playing years with the Ginebra San Miguel franchise in the Philippine Basketball Association.
Locsin played for the RP Youth team in 1990 before suiting up for back-to-back UAAP titlist De La Salle Green Archers.
He had a brief stint with Triple-V Foodmasters in the Philippine Basketball League prior to its disbandment and then played for Nikon Electric Fan which completed a cinderella finish in the PBL.
When 6-9 Marlou Aquino, the most sought-after rookie, was out of the picture in the 1994 PBA draft, Ginebra, now renamed Tondeña 65, and the team that will pick first in the amateur draft, went for the next best option in Noli Locsin, a burly 6-3 power forward who can barrel his way into the toughest walls of the defenders.
A consistent low post threat, Locsin closed the size gap with his strength and skill although he began to fade out as soon as he parted ways with Jaworski.
