Jercules Tangkay led the Welcoat juggernaught with 17 points, seven of which coming in the first quarter when the Paint Masters started to pull away.
Irvin Sotto led three other teammates in double figures with 14 points but lacked bench support as the Juicers absorbed their fourth defeat against two triumphs.
"Slowly but surely, we’re starting to play like a team," said Welcoat coach Leo Austria. "Hopefully, we could sustain this kind of momentum although we really miss Paul Artadi."
Artadi, part of the team that whipped Dazz Dishwashing Liquid in last year’s Challenge Cup finals, has taken a leave of absence from the team because of his commitment with his school team University of the East.
