I only read OP and a couple responses so forgive me if this has already been said. Maybe playing both rec and travel is messing with her timing? My DD in 12u hates slow pitchers, and prefers heat. When she faces slower pitchers she actually struggles some, we are working on that. My daughter also hits a lot of balls to right side but she is taught to by her HC, anything except inside pitches go up the middle or to opposite for her, she rarely pulls the ball. It is obviously not good if she is hitting little dinkers to the 2B or SS.
