Playing the game one pitch at a time truly is a process that you must practice in order to be able to do it during games. Baseball players are always looking for consistency. Consistency comes from understanding the process and what it takes to get better today. Never take a pitch off. Never give up an at bat. Work to develop feel every time we play the game. If you continue to focus on results, you might develop a feeling of helplessness because that is what the past has taught you.
Commit to the process because that is what is failing you. The process is in your control. Will your process make a difference today? If not, then your process has failed you. Grind it out and make sure you win today!
