Never shorts.
I always liked the over the shoe baseball look, and have tried for years but the girls absolutely were against it. This past year, they wore fastpitch pants but broke tradition and all wore nike short ball caps. Maybe ill try again this yaer.
Our HS switched from shorts to pants in 2010, those that were going to slide, were still going to be those that slid, regardless of the shorts.....Good players play period..... Shorts were a Bi#% when they played in the snow/cold games though, but they did............Years ago, I remember hearing a college coach say that girls that wear shorts are less likely to slide. They don't want to skin themselves up. Her program switched to pants.
