My 10yo DD rhp consistently steps left of the power line. When pitching to either side of the plate she steps about 8-10 inches left of the power line. Her accuracy is good. Decent speed 46-47 mph. She's #1 pitcher on her tb team. Last tournament she had 4 walks in 10 innings. We practice staying on the power line but she says it feels better when she steps left. Whats the downside?
