The final score was 106-76 for a 30-point difference that somehow eased the stigma of the 96-91 loss the Gems suffered at the hands of the RCPI Negros Slashers at the same venue on Saturday.
It also enabled the Gems of coach Francis Rodriguez to gain a share of the lead with the Slashers and the Olongapo Volunteers. They all carry 4-win, 1-loss slates.
The Gems actually started slowly, even allowing the Amigos to post a 21-19 first quarter lead.
Bruce Dacia and Jercules Tangkay found their range, however, allowing the Gems to gain control by halftime, 69-54.
Ahead by 15 points at the end of the third quarter, the Gems never wavered to push back the Amigos to the cellar of the eight-team field with a 1-5 card.
The high-flying Dacia drilled in 28 points and had five steals, while Tangkay, another power leaper, complemented him with 20 points and 12 rebounds.
Marc Pingris, a prime candidate for Discovery of the Year, also did well with 11 points, 12 rebounds and 6 assists for the Gems, whose trapping defense netted them 12 Blitz 3s.
The Amigos drew 16 points and 11 rebounds from 6-foot-5 Ricky Calimag, but Top Gun Peter Naron was held to 11 points.
