Yeah, I can see your complaint. I think it is something that is progressing in the game. What I mean is that two years ago the ball never hit the pitcher, then last year it hit him, but there was no 'result' in game (the commentary never mentioned it, and he didn't 'limp' around etc..), now this year it hits him and then he limps around etc...
I'm not sure what the end result is supposed to be (1 or 2 years down the road). I think it hits them too many times. I don't recall seeing that many hits in real life. They somehow need to find the happy medium, because I don't think you'd be happy right now if the guy was injured every time.
There clearly were some 'tweaks' to that system in the most recent patch. I think the pitcher handles more balls in that area now, which should reduce the number that ricochet of him.
It does seem that nearly every ball that ricochet's off him is fielded cleanly and you end up getting thrown out.
