If the pitcher or hitter start experiencing trouble, and everything starts getting a little ragged, regroup and get back to basics. Remember, all good pitchers have outstanding games where everything seems to come easy and natural. The beauty of baseball is that each team gets the same number of outs. As long as the offense has one strike left, the other team is in jeopardy. That supposedly last strike is the pitcher's opportunity to start one of those beautiful streaks when everything flows and goes.
All pitchers are more than willing to discuss pitching.
Watch them in action. If you do not understand why they do something, ask them after the game. They may also be able to pick up flaws in your delivery that could be causing you problems. Any pictures, stills or moving, of your pitching motion are good sources of checking out your delivery at different points. A slight difference in stance, step, or hand turn can make a difference.
