The first settlers from the Paoay area in Ilocos Norte arrived in 1830, and founded the first Spanish settlement that developed into what is now San Antonio.

[citation needed] San Antonio, influenced by the presence of the United States Naval Communication Station in the late '50s, is the baseball and softball capital of Zambales.

In the early '80s, JJ Henry & Chuck Jones of FRA Branch 367 (US Navy retirees) living in San Antonio, further enhanced the enthusiasm for the sport through the Shipmates, a team of 10- to 12-year-old boys coming from the different barangays who competed in the PABA (Philippine Amateur Baseball Association) Invitational.

In 1985, the core of the team intact & playing for TR Yangco Educational Institute, the Shipmates coached by Butch Echiverre, won the baseball gold in the CLRAA (Central Luzon Regional Athletic Association), a first for Zambales.

After the eruption of Mt Pinatubo in 1991, due to the destruction of the playing fields and the withdrawal of the US bases, support for the baseball program dwindled.

From its humble beginnings at a place called "Kubo," presently, the Zambales Darters Federation is considered as one of the best dart organizations in the country for having hosted several national competitions.

Its "no-school, no-play" policy is now adopted nationwide and the NDFP (National Darts Federation of the Philippines) conferred the President's Award to the group during the Darterong Pinoy 2012.
