The greatest and brightest kid I ever had catch for our summer travel team (not the most talented) played this off as beautifully as any I have ever seen. This goes back about 12 years.
2 outs, 2-2 count, catcher presumed strike three called...bounces out of his stance and jogs to the dugout. Ump yells "ball". Catcher continues running over to dugout, without breaking stride, and finds a spare towel hanging from a fence. He thoroughly wipes his eyes and face, puts his mask back on, and jogs back to home plate. Next pitch was popped up and caught.
At the beginning of the next inning, while catcher was warming up pitcher, he and ump had a small laugh. After the inning I asked him what went on.
He said the ump asked him what was wrong the previous inning when he went over to get a towel and forgot to ask for time. Catcher told the ump he figured he better wipe the sweat out of his eyes cause he thought the previous pitch was a strike.
