High rate of speed as used by most announcers is actually not correct. Speed is the rate at which distance changes with time. Speed already expresses a rate. What one can deduce is that they probably meant to emphasize more on the how fast a sport is proceeding. Ordinarily saying speed would have been fine.

According to physics, the rate of change of speed is acceleration. Acceleration is the change in velocity with time. A body is said to be accelerating if its velocity is constantly changing.
