MANILA - Barangay Ginebra kept its title defense hopes alive in the PBA Governors' Cup with a 104-92 quarterfinal win against TNT Tropang Giga on Wednesday night at the Smart Araneta Coliseum in Quezon City. With the win, the Gin Kings are now halfway into completely overcoming a twice-to-beat disadvantage as the Tropang Giga's bid to complete the league's first two-conference grand slam hit a temporary snag that could become bigger if they lose again in the rubber match on Saturday night. Ginebra quickly sizzled early on as the team raced to a 28-14 lead over TNT at the end of the first quarter. But the Tropang Giga responded with a 31-point second quarter, and eventually came to within one, 70-71, entering the fourth period. However, the Gin Kings recovered in time and pulled away for good in the final frame with a 33-point blast.
