What constitutes a slump?
When the answer is hitting poorly for 10 ABs. Does that mean hitting poorly or not getting as many hits as you might like? You can have 7 out of 10 quality ABs and be 1 for 10. So, when you ask hitting poorly, I take it as you had poor ABs 10 times. Thats a slump and needs addressing. When I see players slumping, they usually have abandoned the yes, yes, yes approach and are batting defensively. Example: Count is 3 and 1. Player is thinking, I don't want to swing at ball 4 (should be thinking 3 and 1, I going to smoke this one) then player indecisively frails at the ball down the middle with an all-arm swing and hits a weak grounder to the 2nd baseman. Slumps are usually mental.
