2019–20 Sarangani Marlins season

The 2019–20 Sarangani Marlins season was the inaugural season of the franchise in the Maharlika Pilipinas Basketball League (MPBL).

Starting out as the Soccsksargen Marlins, the team finished the season with just one win in the 30-game season. It is the first one-win season since the league's national expansion and just the second ever. By winning percentage, it is also the worst season by any team in a single season. The team has also been the subject of a game-fixing scandal after going 0–18.

The team's only home game this season was held at the Sarangani Capitol Gymnasium in Alabel, which is also where they claimed their lone victory as well.

Game-fixing scandal
On November 4, 2019, the league suspended the Marlins team over game-fixing allegations. League founder and then-Senator Manny Pacquiao ensured that the persons involved in the scandal would face appropriate charges and reminded other teams that the league has zero tolerance towards "any form of cheating and other unsportsmanlike behavior."

A week later, league commissioner Kenneth Duremdes, who was assisted by the National Bureau of Investigation, then filed criminal complaints to 21 persons involved in the scandal, which included three Chinese nationals and ten Marlins players before the Department of Justice. On April 16, 2021, the DOJ would indict 17 persons with criminal charges.
