Returning to the South Division, Rizal made a splash by soaring to a 10–5 record in their first fifteen games, a far cry from their previous two seasons, where they were had the worst record of the division. Despite that, they would fall in their last six games to finish the regular season 10–11, one game below .500. It is still enough for the Golden Coolers to clinch the sixth seed in the South Division.
Rizal was matched against third-seeded Sarangani, who are six games ahead, but it did not make any difference as the Golden Coolers stunned the Marlins in a Division Quarterfinals sweep.[1] They would, however, be swept by the Batangas City Embassy Chill in the Division Semifinals.[2]
Rizal was one of 22 teams that took part in the 2021 MPBL Invitational, competing as Rizal Emkai Xentromall. They would fail to make the playoffs after finishing in fifth place in Group D.[3]
