Davao Occidental Tigers–San Juan Knights rivalry

The rivalry began during the Maharlika Pilipinas Basketball League's 2018–19 season, when both the Davao Occidental Tigers and San Juan Knights joined as expansion teams.

Their first regular season match-up came on December 18, 2018, at Rizal Memorial Colleges in Davao City, with the host Tigers winning the game 87–75.

Emman Calo then attempted a two-point field goal that unfortunately missed, giving San Juan their first MPBL championship.

[2][3] In time for FilBasket's inaugural tournament, the 2021 Subic Championship, the Tigers would sign John Wilson, who won the 2020 MPBL Most Valuable Player award with San Juan.

Both teams wouldn't meet in the playoffs, however, as the Tigers advanced to the finals while the Kings were eliminated in the semifinals by the Pampanga G Lanterns.

John Wilson is among the players who played for both Davao Occidental and San Juan.
