Here's the situation:
11U tournament game following high school rules. Runner on second and third two outs. There is a two umpire crew. A fly ball is hit to medium deep centerfield. The catch is made and runner from third tags and comes home. The runner on second also tags (or fails to tag) and advances to third. On the play, the ball is thrown home for a possible play. It is fielded cleanly by the catcher. His coach tells him to throw to second. He does, and the second baseman steps on second base. The field umpire signals and vocally says: "safe!" The coach of the defensive team calls time. He talks to the home plate umpire for some three to four minutes. He walks back to the dugout. The umpire puts the ball in play. The pitcher steps off and throws to second. The homeplate umpire then calls the runner who failed to tag, out. The field ump did not ask for help on the call.
I argued the call on the following:
• The throw to second by the catcher on the original play was a legal and acknowledged appeal and the field umpire, who was at second base, called the player safe. The second appeal was illegal because it was the same appeal, on the same player, at the same base and only one such appeal is allowed.
