[4] He is also a regular fixture at the Asian Bowling circuit culminating in a runner-up finish in the Grand Slam finals in 2009.

Notably, he discovered and recruited Singapore-based bowler Zach Sales Ramin to the Philippine national youth development squad.

Under Rivera's mentorship, Ramin achieved significant milestones, including becoming the youngest-ever winner and the first Filipino male to clinch the Singapore Open title since 1965.

Ramin also played a crucial role in the Philippine boys' team's historic victory at the 21st Asian Youth Tenpin Bowling Championships in Bangkok, Thailand, where they secured the overall crown for the first time.

Rivera's dedication to nurturing young athletes continues to contribute to the resurgence of Philippine bowling on the international stage.
