Daisuke Matsuzaka
The "Power Pro" series raised some controversy in Japan with its use of the term "Gyroball", a term made popular by Japanese pitcher Daisuke Matsuzaka when he signed with the Boston Red Sox. The Gyroball appears not as a pitch usable in a baseball game, but as one of the special abilities assigned to particular pitchers. In Pawapuro, pitchers that have the Gyroball ability get increased velocity on their fastball, which is completely different from the actual definition of a Gyroball (a pitch with a spin resembling that of a slider). "Power Pro" and other baseball manga (which also give misinterpretations of the Gyroball) have given the impression that the Gyroball is an all-powerful strike out pitch, which it is not. Several professional pitchers (including classic players) are given this ability in the game, but Daisuke Matsuzaka is not given the Gyroball ability in any of the game's installments.
