In 2007, the ONW baseball team became co-Sunflower League champions for the first time in school history. The team finished with a record of 12–8. The squad reached the Regional Championship game in 2004 and 2005 but fell one game short of the state tournament each time. In the 2003–04 season, the Ravens entered into regional play as the bottom seed and drew Mill Valley High School, the  1 team in 5A. The Ravens defeated Mill Valley in one of the biggest upsets in Kansas high school baseball history.
