One time when I was playing little league baseball I hit a line drive ball that went to the shortstop player.
Out of the corner of my eye I saw the shortstop jump up and catch the ball.
You know what I did? I stopped running, turned around and started walking back to the dugout.
What I did not see was the shortstop player dropped the ball, picked it up, then threw the ball to first base. I did not see it because I had my head down as I walked back to the dugout.
What did I learn from that? You never give up, ever. You run as fast and as hard as you can. When the umpire calls you out, then you are out, and not a second before.
