A pitcher needs two pitches, one they're looking for and one to cross them up.
Hitting is timing. Pitching is upsetting timing.
Once (Stan) Musial timed your fastball, your infielders were in jeopardy.
You don't just throw the ball - you propel it.
Twenty games is the magic figure for pitchers - .300 is the magic figures for batters. It pays off in salary and reputation. And those are the two things that keep a ballplayer in business.
I'm probably the only guy who worked for (Casey) Stengel before and after he was a genius.
