In what is a first for the NSW Women's Baseball League, the six A grade teams will play a round, following a girls' development day.

Female Program Manager for NSW Country Baseball Eryn Shipp plays in the Illawarra men's baseball competition for Shoalhaven Mariners.

She believes Illawarra has the talent to form its own women's team in the Sydney-based competition.

"This is a great opportunity for girls to mix it with some of the best female players that NSW has to offer. Women's baseball is growing and we should be part of it," Shipp said.

"Currently, our girls and women are travelling north to play with clubs in the NSW Women's Baseball League.

"We have the talent in the Illawarra and South Coast, and should be focusing on competing in our own right."

The A grade matches will feature Central Coast vs Greenway and Ryde vs Cronulla from 1pm, and Baulkham Hill vs Blacktown and Central Coast vs Cronulla from 3pm.

Chairman of the NSW Women's Baseball League Steve Taylor said bringing 80 of the best women's baseballers to Wollongong was important in expanding the sport.

"We're happy to support the Illawarra and South Coast baseball community and see this as a step in building female participation in the sport, and showing the girls what can be achieved," Taylor said.
