The win helped move Edwin Cabalida's men top of the table two points ahead of second-placed Kaya, and a win over Loyola Meralco Sparks in their final game of the season next Tuesday will be enough to secure the title.
Izzeldin Elhabbib was the star of the show for Global as he laid on an assist for Alex Obiang to open the scoring in the 11th minute, before putting them firmly in control by grabbing one of his own 13 minutes later.
The Sudanese striker then grabbed his second a minute after the hour mark, before Patrick Reichelt capped off a dominant display from Global by adding a fourth in the 72nd minute.
The win also ends Loyola's title hopes as they are now five points behind the leaders, while Kaya will need a win in their final game against Stallion Gilligan's to have any chance of pipping Global to the crown.
