A World Series Example: Be Explicit
Uploaded: Oct 23, 2013
Game one, second inning; St. Louis's Wainwright pitching, high pop up. Looks like he signals that he'll catch it. Catcher Molina comes running up, but defers to Wainwright's "signal." They are standing a few feet apart. Either one could easily catch it.
The ball falls to the ground between them. Thud.
Runner goes to first.
Couples need to be explicit. Even when it seems like the signals have been given.
