We have used a stategy for years. When we have two very good pitchers that are equal in ability but have differnt styles. We rotate them each inning, so the batter doesn't see the same pitcher back to back. It really plays mind game with the hitters. This year I have a pitching coach that won't allow his girl to do this, as he stated this will cause an injury. Never heard this before, in softball, but yes in baseball. I don't want to take the risk. Anyone else heard of this issue. If Bill Hillhouse reads this I would like his insight.
