MANILA - San Miguel Beermen forged a showdown with TNT Tropang Giga in the championship round of the PBA Philippine Cup after clobbering Meralco Bolts, 100-89, on Wednesday night at the Smart Araneta Coliseum. Three nights after blowing a huge lead late in Game 6, SMB found itself in another Meralco comeback, but this time, the former held on.
