Before every game, one of the linchpins of the Yankees’ talented bullpen, Adam Ottavino, finds a spot in the clubhouse to sit and write.
To combat the six-month mental minefield of self-doubt that is baseball’s regular season, Ottavino has found solace in a daily routine of writing in a journal. In it, he tracks how he cares for his powerful right arm, how he sharpens his focus, how he plans to attack an opposing lineup and, sometimes, he gives himself a pep talk by writing such messages as, “I am a great pitcher.”
“Sometimes you slip into that natural state that you’re getting beat out there,” Ottavino said. “Or maybe you’re starting to doubt your ability a little bit. Sometimes it’s important to remember how good you really are and the many tens of thousands of good pitches you’ve made.
“So I just try to remind myself, ‘I can do whatever I want with my breaking ball.’ Or, ‘I can throw perfect fastballs.’”
There’s some good advice in here for just life in general.
