TNT goes for a repeat of its finals stint last year while San Miguel Beer eyes a return to the title playoff after missing it in the last two conferences.
This makes one of two compelling semifinals face-offs pitting A-1 ball clubs from giant corporations with their rivalry in the corporate world.
The Tropang Giga and the Beermen begin their side of the Final Four showdown at 4:35 p.m. Sunday at the Don Honorio Ventura State U Gym in Bacolor, Pampanga - a duel between two teams raring to take the throne vacated by the Barangay Ginebra Kings.
TNT is a hungry ball club, having been without a crown since its 2015 Commissioner's Cup title run.
San Miguel, meanwhile, is a ball club out to prove its era as a dominant champion is not yet over.
Both teams tweaked their lineups and prepared hard for a shot at glory in this tourney.
TNT brought back coach Chot Reyes who then called on Kelly Williams to return from retirement, picked Mikey Williams from the rookie draft and also recruited Brian Heruela, Dave Marcelo, Chris Exciminiano, Glenn Khobuntin, Chris Javier and Gryann Mendoza.
San Miguel, on the other hand, welcomed back June Mar Fajardo and acquired scoring champ CJ Perez in a major trade deal.
The Tropang Texters have had a success that they want to extend further to the finals.
They've been a dominant squad, winning 11 of 12 games.
The Beermen settled for a fourth-place finish in the elims with a 7-4 win-loss card but now ride the momentum of a two-game sweep of the NorthPort Batang Pier in the quarterfinals.
Another good news for San Miguel is that everyone is back in harness, giving coach Leo Austria a deep lineup to throw into battle against TNT led by the two Williamses, Cayson Castro, RR Pogoy and Troy Rosario.
It's likely to be a battle of styles of play.
San Miguel is No. 1 in offense (97.8) and field goal percentage (45.4) but is second in most turnovers (17.2). TNT is No. 2 in defense (78.9), No. 1 in steals (9.5), No. 1 in turnover points (22.7), No. 1 in field goal percentage allowed (37.4) and No. 1 in opponents' turnovers (18.9).
