My son is also 15 and began umpiring in the fall when he was 14. I was interested to see how he would handle the preasure of adults getting on him about calls. I went to a few of the games and set in the stands not telling anyone he was my son and boy was it interesting listening to the parents. On one play the 7 year old clearly missed first base and was called out. Because he crossed the bag before the ball got there the parents thought the kid should have been safe and went balistic yelling what is this the majors. I almost fell over trying to hold back the laughter. I was as proud of the way my son handled the situation as I am when he pitches a great game. By the way I only attended the first couple of games he umpired then I left him on his own. Overall a great experience that he will continue with in the spring and summer.
