The pair of Justin Brownlee and Jeff Chan led a balanced offensive by the Kings which was most evident in a searing 21-2 run over a seven-minute span in the fourth quarter that fully put the game away.
Before the Elasto Painters knew what hit them, they were behind by 78-102 and were left looking forward to bouncing back in Game 2 of the best-of-five series Tusday.
Reggie Johnson led Rain or Shine with 30 points and 13 rebounds while James Yap added 15 and Ed Daquioag 10.
The likes of Raymond Almazan, Chris Tiu and Maverick Ahanmisi did not produce their usual points, however, with Almazan even going scoreless.
In contrast, Ginebra’s offensive display was headlined by Brownlee’s game highs of 35 points and 14 rebounds on top of nine assists.
Chan also came off the bench to explode for 21 points, 10 coming in the final canto that broke the Kings off from an 81-76 count and fully quashed the hopes of his original PBA team.
