Here's a play I saw tonight. 13u. OBR
Base loaded. No outs.
Line drive to F4 who stabs at, and gloves, but drops, the ball.
No way it was an intentional drop ... made a good attempt at it.
(I can tell you that I clearly saw/heard the umpire call the ball down).
R2 and R3 freeze, but R1 is way off the bag.
F4, who evidently had a brain lock, or maybe he thought he caught the ball, throws to F3 and barely gets the B/R as R1 (who also thinks the ball is caught) dives back in. No attempt by F3 to tag R1. R2 and R3 retreated ... both as confused as R1 (Despite their 3B coach trying to send both of them).
So ... no one advanced. All three runners remained in place after what was scored simply a 4-3 routine ground out.
Defensive coach came out and tried to explain why he had a DP. All this time, the batter never left 1B. You had the batter (already out) and R1 standing together on 1B while the umpires talked down the DC. Finally the batter trotted off the field when they sent the DC back to his dugout.
