i remember watching an episode on espn classic where PDW was bowling ummm, the name isn't coming to mind, but it showed the speed that he was bowling his strike ball and it was 20 mph, one thing we need to keep in mind is that they adjust their speeds so often that its hard to say if they are throwing slower or faster than an average bowler, on the cheetah sure they throw it fast, on the shark, with the exception of a few power players they throw it slower. but what those speeds are is hard to say. 17mph i'd say is the average maybe faster
