In 2010, a merger between Liga Pilipinas and the Philippine Basketball League was proposed.

Through an agreement between Liga Pilipinas and the PBL, a joint tournament was held starting in June 2010.

The joint tournament was held as a dry-run of the proposed developmental league.

The tournament started on June 9, 2010, and ended on September 13, 2010, when the M. Lhuillier Kwarta Padala-Cebu Niños became the TOP Champions by defeating the Misamis Oriental Meteors in a best-of-five final, 3-2.

After the tournament, merger talks between the 2 leagues went sour and was put off for good.
