I go to little league games in the area and watch a dad who has to fill-in on the bases for one reason or another. Dad comes in, "oh, I know baseball, this shouldn't be hard". And, by the end of the night, his tune is "I never want to do that again." Raises hand. Did it 3 times and it actually wasn't bad, didn't miss any calls. Did have one where I called the runner out at first on a groundball until I saw the ball trickle out of the 1B glove and immediately signaled safe. Couldn't see it right away from behind and the 1B coach who could gave me quite the glare. I knew enough to listen for the catch and watch the bag. Cabrerra's throw wasn't particularly hard and I wonder if Joyce couldn't hear the ball hit the glove. He needed to be looking at the bag and not for any bobble which didn't happen anyway. JB is quite offbase with that opinion.
