2018 National Pro Fastpitch season

The 2018 National Pro Fastpitch season was the 15th season of professional softball under the name National Pro Fastpitch (NPF) for the only professional women's softball league in the United States. From 1997 to 2002, NPF operated under the names Women's Pro Fastpitch (WPF) and Women's Pro Softball League (WPSL). Each year, the playoff teams battle for the Cowles Cup.
