The Roxas Vanguards was formed by the municipal government of Roxas, Zamboanga del Norte under Mayor Jan Hendrik Vallecer upon the suggestion of Zamboanga del Norte governor Roberto Uy to send a team for the Pilipinas VisMin Super Cup.[1]
In the First Conference, Roxas finished the elimination round of the Mindanao leg in fourth place with a 5–3 record. In the playoffs, they won by default against MisOr Brew Authoritea in Quarterfinals Round 1 then swept third-seeded Pagadian in Quarterfinals Round 2. In the Semifinals, they faced against JPS Zamboanga City where they won in three games to advance to the Mindanao Finals against the undefeated Basilan Peace Riders. Unfortunately for Roxas, they would be swept by Basilan.[2]
Roxas then returned for the Second Conference, finishing fifth with a 6–6 record. They would lose against the Zamboanga Sibugay Warriors in the Quarterfinals, which had a twice-to-beat advantage.[3]
The Vanguards then moved to the Pilipinas Super League in 2022, becoming one of its charter teams. Finishing with an 11–3 record, Roxas advanced to the playoffs as the second seed. They would lose to the Cagayan de Oro Higalas in the Semifinals, putting the Vanguards in the Battle for Third. It turned out to be a rematch of the Mindanao Finals of the 2021 VisMin First Conference, as they went against the Basilan Peace Riders in a single-game series. Roxas beat Basilan 66–59 to take the third place spot.
