Is there some sort of wall starting pitchers hit around the middle of ST? Our starting pitcher outings have gotten worse and worse.
No, it's nothing like that most likely. Most starters work on different things in spring training - rather than trying to pitch an actual game
Spring training is indicative of pretty much nothing, particularly for pitchers. They just want to get their work in, build up their arm strength, work on particular things, stay healthy and get ready.
I wouldn't worry about it too much.
