TNT lines itself for a first-ever grand slam Sunday when Season 2 of the PBA 3×3 comes to an end.

The Tropang Giga go for a historic sweep of the season with the Third Conference grand finals set at Robinsons Place in Las Piñas starting at 11 a.m.

The telecommunication franchise is seeded no. 1 in the 10-team finale after earning the most number of tour points with 430 after the six-leg tournament.

Almond Vosotros and Co. topped the First Conference grand finals by beating Platinum Karaoke, and then repeated in the Second Conference over Cavitex.

Dating back from Season 1, TNT won the grand finals three straight times after likewise ruling the Third Conference in July last year.

Seeded with them outright in the knockout stage are no. 2 Cavitex, third seed Meralco, and no. 4 Barangay Ginebra.

The six other teams which qualified will see action in a pool play to determine the four other teams to complete the quarterfinals cast.
