The World Ranking Masters was ten-pin bowling's international ranking system, as with professional tennis. It was governed by the World Tenpin Bowling Association (WTBA). The rankings were formulated at the end of the three international tours, the European, Americas (not "American", although it does cover the US) and Asian tours.
The last World Ranking Masters was conducted by WTBA in 2009.
