Two quick first-half goals set the tone for a statement victory, with Sailors goalkeeper Hassan Sunny culpable for both.
The 36-year-old first flapped at a corner to allow Tan to sweep home, before scuffing an attempted clearance that led to Doi slotting into an empty net.
The Cheetahs sealed the three points after the break, with Doi’s shot from a tight angle somehow creeping in at the near post – rendering a late Plazibat tap-in immaterial.
