You state that your son played LL ball for just for the fun of it not to make the All-Star team.
My son had been playing with one team through his 11th year. Because that team was made up of twelve 12 year olders and just three 11 year olders the team needed all new players. The coach and the sponsor decided not to field the 12 year old team as the 12's moved up to the Seniors.
My son, than had to be picked up by another team in the draft, which allowed a completely new team that had never competed before at the majors to draft him. The coach brought all of his minor leaguers up to play their first year at the majors. My son was the only 12 year older on the team. They ended with a losing record. None-the-less my son was given the starting pitcher's job for the 12 year old All-Stars.
This was because the year previously when he had pitched for the All-Stars team the year before, he helped them win a championship. On that occasion it was for the district championship game of the 12 year old majors, he was 11 at the time.
The game was tied at the end of 7th and the umpires called the game due to darkness. So the next day the pitcher from the previous day, started and the game, went into the bottom of the 10th inning with our team ahead by one run. Then with two outs he loaded the bases.
The coach, then brought in my son. With the bases loaded and two outs, and the stands jam packed with people screaming, you could've cut the tension in the air with a knife. My son takes the batter to 3 and 2 where the batter then fouls off several pitches. Now the place is quiet as a church mouse, and no one is saying a word. My son winds up throws the pitch and there is a collective roar as the ball is grounded to the backhand side of 3rd. The 3rd baseman fields the ball going away toward the foul line turns and throws off balance to get the runner at first...great play, game over, we win the championship.
Next day the newpapers had headlines extolling the play by the 3rd baseman, not a single word about my son. We got calls most of the day from people who were just dismayed that my son had being so dismissed by the league for his effort. My son didn't care, his comment was that he was more concerned they had misspelled his teammates name, and he wandered whether his teammate would get full credit for such a great play. He said, "well Dad he did save my butt."
My son says he doesn't care about awards (All-Stars), etc. He's the one that plays because he loves the game. He gets awards and we put them in his trophy case where they collect dust.
He just won a game ball in his last tournament, didn't even mention it to me until I asked him if the team was getting anything like ribbons, pins, or trophies. I'm the one, I must admit, that keeps track of them. He doesn't even look at them. I guess I'm the one that takes a certain amount of pride in his accomplishments.
But should a parent want his son to play All-Stars, yes; is it worth it to have your son playing? You betsha, if not but just for the memories. When it's over each pin, ribbon, trophy will bring back those instances of sheer and stark terror, and also those of great joy.
My point is, if your son loves baseball enough just to want to play, and he's good enough to be invited to play All-Stars, let him do it. It is a great chance for him to compete at the highest level of his age group.
