Great opportunity for you with your 2022... actually would have been even better without the bright spots. It is a big part of the game for every single player and a good checkpoint for seeing how they are handling failure as an individual and as a teammate. They will all struggle/lose and bounce back hundreds, maybe thousands of times. What is important is how they handled themselves in the process. Did he stay positive and battle thru the last pitch? Did he continue to try to lift his teammates or retreat, drop his shoulders or pout? Teaching and parenting opportunity... be sympathetic but don't accept behavior unbecoming of a young man of character.
Also, the approach RJM and baseballmom describes is key. Actively analyze, learn, adjust, be confident, move on.
