I didn't understand it

Rating: 6/10 (11 May 2020)

-I didn't get this movie. There are some pretty heavy events in the life of the main characters, but it's not clear to me why these things are happening to him and why these people target him. And there are big gaps in the life of the main character of which it is unclear to me what happened. I kept watching things will all make sense in the end, but no.
-Granted, I know nothing about baseball, but this could have been about another sport too.
-It may be that I fell asleep somewhere throughout the movie and missed some things, but I'm not rewatching.
