She is 5-foot-1, 115-pounds and throws a sidearm knuckleball that usually registers in the 50 mph range.
She became the first woman to pitch professionally in the United States in a decade, Yoshida showed that she and her sidearm knuckler can hang with the men.
The "Knuckle Princess" was unfazed when a former major leaguer opened the game by bunting for a hit. She had a few knucklers that danced almost as much as those of her idol, Tim Wakefield of the Boston Red Sox. She pitched a scoreless first inning in her debut for the Chico Outlaws of the Golden Baseball League, before struggling a bit by allowing four runs in her final two frames.
Why not? I guess the one way a girl can do well at high levels of baseball is to throw a knuckleball.
