Maharlika Pilipinas Basketball League

Davao Occidental Tigers were established in 2018 as an expansion team in the Maharlika Pilipinas Basketball League. The Tigers were one of three teams to be based in Mindanao at the time, alongside General Santos and Zamboanga. The team led by Mark Yee saw immediate success, clinching the South Division's top seed with a 20–5 record.

In the playoffs, Tigers swept Cebu City in the First Round, as well as Bacoor City in the Division Semifinals. In the South Division Finals, they met the defending champion Batangas City Athletics. Although Batangas City forced a game 3 in overtime, the series was won by Davao Occidental and they faced San Juan Knights in the 2019 MPBL Finals. The series went back-and-forth with both teams alternating wins, all coming down to a winner-take-all game in Davao City. Tigers led by three points heading into the last minute, however, Jhonard Clarito scored four consecutive points for San Juan as Davao Occidental lost the game and the series by a single point.

Looking to come back after a stunning finals loss, Davao Occidental kept the same core heading into the 2019–20 season. Once again the team clinched the top seed in the South Division with a record of 26–4. This made Davao Occidental Tigers the first, and currently only, MPBL team to clinch the best division record in back-to-back seasons.

To begin their 2020 playoff campaign, Tigers first beat Bicol in three games. They then met Zamboanga in the Division Semifinals, with the first game ending up as the lowest-scoring in the MPBL history. Davao Occidental then matched up with Basilan in the South Division Finals. With the series tied 1–1, it saw an abrupt ending following the suspension of the playoffs due to the COVID-19 pandemic in the Philippines. When the playoffs continued the following year, multiple Basilan members were tested positive for the virus, thus the series was awarded to Davao Occidental, creating a Finals rematch against San Juan. Davao Occidental got their revenge and won the series in four games, thus winning their first league championship in franchise history.
