I once got fastball pitch of 150 km/h (93 mph) in the baseball game of Wii Sports. I only did it only once, all my other fastball are much slower than that usually 100 mph (62 mph).
I don't know how I was able to throw a pitch like that. I don't remember what technique did I used. I would like to know which motion or pitching mechanic I need to achieve these speeds.

Another tip compared it to trying to swat a fly - a sharp downward motion.
