To mark the 50th Singapore International Open, the Singapore Bowling Federation (SBF) is aiming to raise at least $50,000 for the event's adopted charity SPD, which supports people with disabilities. The SBF held a bowling event for SPD members at SingaporeBowling@Rifle Range yesterday. Teams painted bowling pins which were later auctioned to raise money for SPD. The Open will also be held at the same venue from May 26-June 9.
