POWERHOUSE squads San Miguel Beer (SMB) and TNT collide in a titanic matchup, highlighting the Saturday schedule of the PBA Season 50 Governors' Cup at the Ynares Center in Antipolo City. The Beermen (7-2) and the Tropang 5G (5-4) square off at 7:30 p.m. TNT managed to squeak past SMB, 93-89, in overtime in their first meeting over a month ago at the SM Mall of Asia Arena. Kim Aurin came through with a game-high 22 points, hitting big shots in the extra period to bail TNT out. That game saw the Tropang 5G play with a depleted roster as veterans Roger Pogoy, Calvin Oftana, Jordan Heading, and Jayson Castro were still out due to various injuries at that time. But their second face off on Saturday will feature a TNT side that is at full strength as the four key players are back in harness. Oftana actually tossed in 31 points in leading TNT past Terrafirma, 116-92, at the resumption of the tournament last Wednesday. TNT also saw new import Nick Hornsby with a solid PBA debut of 26 points as he took the spot of Rahlir Hollis-Jefferson. San Miguel, though, is on a three-game roll just before the tournament took a temporary seven-week halt to give way to the international tournaments of Gilas Pilipinas. The Beermen piled up three straight wins prior to the break, routing the Converge FiberXers, 126-114, the Macau Giant Pandas, 131-79, and the Titan Ultra Giant Risers, 143-113.  High-scoring import George King will be leading the SMB charge, along with June Mar Fajardo, CJ Perez, Don Trollano and reigning PBA 3-point king Jerrick Ahanmisi. Meanwhile, Terrafirma fights for playoff life and needs to win against a decimated Macau side on Saturday. The Dyip suffered back-to-back blowout defeats against Converge and TNT and dropped to a 3-6 win-loss record.  Macau, which enters the game without its core of Ramon Cao, Damian Chonqui, and Jenning Leung, is also fighting for its postseason hopes. The Giant Pandas are coming off humiliating 138-78 beating from the NLEX Road Warriors, marking the worst-ever defeat in league history.  Macau carries an anemic 2-7 record in Group A.
