I didn't do a complete box score breakdown.... Looking at their gamechanger, for the entire summer, they went 21-10, Pitching breakdown, by innings, was 100, 56, 3.@Cougars how many of those 41 innings were from her coming in relieve the number 2 pitcher??
If you are a coach that doesn't have 2 pitchers who can beat anybody you plan on playing and a third who can come in relief and give you a good 2 or 3 innings, you shouldn't expect to win tournaments and still be able to safely use your pitchers.
We have other threads about what's healthy, or how long until arms get tired. I just know that specifically about "how many pitchers", in my "B" level experience, very few of the teams have a #3 that they would trust with very many "important" innings.
