Joe McCarthy 10 commandments for a Mlb manager

Joe McCarthy’s “10 Commandments for Success in the Majors”:
-Nobody ever became a ballplayer by walking after a ball.
-You will never become a .300 hitter unless you take the bat off your shoulder.
-An outfielder who throws in back of a runner is locking the barn after the horse is stolen.
-Keep your head up and you may not have to keep it down.
-When you start to slide, SLIDE. He who changes his mind may have to change a good leg for a bad one.
-Do not alibi on bad hops. Anyone can field the good ones.
-Always run them out. You never can tell.
-Do not quit.
-Try not to find too much fault with the umpires. You cannot expect them to be as perfect as you are.
-A pitcher who hasn’t control hasn’t anything.
