No, not really. The myth that propagates through the lower levels of softball that it is "OK to have a marginal breaking pitch". Parents like to believe that myth because it allows them to believe their DD is exceptional when in fact she is mediocre.
I didn't say that it was OK to believe a marginal pitch is going to get it done. I said it doesn't necessarily have to always be an overpowering drop ball/rise ball that is the pitch we are talking about. It is not OK to rely on bad pitches or pitches that are not well located or don't move and so on - but it also doesn't always have to be overpowering or a massively breaking pitch to be effective either. There is a lot of Strike Out counting in softball pitching at the moment rather than 'Out' counting. The pop up or the ground ball out counts just the same. There are many ways to get it done because if there is only one possible way eventually that way wont work.
A "good" pitcher (someone who is effective at the collegiate level) has control of the location and has at least one really good vertically breaking pitch.
I can mostly agree here. You need to have mastered more than one type of pitch to be successful. A pitch that moves on different planes especially with variety and location skills is one of the tools you will need to have a chance of being successful. You throw a bad curve there is a chance it is going to get hit - just the same as if you throw a bad drop ball or any other pitch.
Then she is not a good hitter. Good hitters don't chase balls out of the strike zone unless it is a nasty breaking pitch.
Here I will disagree in general because it goes against what I see every weekend, at college games and also in baseball. Batters swing at a lot of good and bad pitches out of the zone. You look at location of pitches from any pitchers with control and they are going spend a lot of time working either at the edge of the strike zone, just out of it or throwing pitchers that start in/end out or start out/end in. It doesn't have to all that 'nasty' of a break or movement for the batter to swing at it especially if you can keep a better unbalanced.
I was watching a replay of Arizona State v Florida from last years CWS and Florida's batters couldn't help themselves on high pitches which were rarely in the strike zone (of course a lot of them were rise balls as that was the main pitch their pitcher used). I think we can all agree Florida are an excellent hitting team though I am still stunned they kept swinging at it batter after batter (at some point their coaching staff needed to say that she is only throwing rise balls - if it is at your numbers let it go). They weren't all nasty breaking pitches they were swinging and missing at either. Lots of other examples out there. I remember a couple of the ESPN broadcasts where they had their k-zone technology in place and if it was anywhere near accurate I remember some games where it seemed that the pitcher NEVER threw a pitch that was a strike but lots of D1 batters were swinging away.
In the specific case I will say the girl is a very good hitter but has an identified flaw when she is at bat that needs correcting. I think we all know lots of batters like this.
