Yukiko Ueno

Yukiko Ueno (上野 由岐子, Ueno Yukiko; born July 22, 1982) is a Japanese professional softball pitcher for Bic Camera Takasaki Bee Queen and Japan women's national softball team. She won a bronze and two gold medals from the 2004, 2008 and 2020 Summer Olympics, respectively. She became the first pitcher ever to throw a perfect game at the Olympics, against China in Athens. With a fastball that tops out at 128 km/h (80 mph), she is widely recognized as the fastest pitcher in women's softball, although her signature pitch is her change-up, which is often cited as the best in the world.
