It's not a good idea for a kid to play just one sport. It can lead to injury and burnout. You have pitchers blowing out elbows in high school or even younger because they have played baseball year round since they were 6. Kids should play a variety of seasonal sports and not just one.

It is parents with unrealistic visions of scholarships or professional careers who push young kids to play a single sport year round.

As the coach of a fall little league baseball team, no, it's mostly kids who love baseball and just want to keep playing. A lot of kids also play travel ball tournaments in the summer which could mean about 5 games over a single weekend. But the only position a you could get burnt out on is pitcher. We always keep track of pitch counts and it'd be a serious issue if any coach went over. It's baseball, a kid is not going to get injured because they had too many at bats, or spent too much time standing in center field. It's perfectly safe for a kids to play one sport all season, with the exception of maybe tackle football, but that's a whole other discussion.

There will always be a small number of parents who push their kids too hard and it's up to the leagues and other coaches to step in when it could be dangerous. That said, the vast majority of kids still practicing baseball in the summer and fall are out there because THEY enjoy it and they themselves want to get better at their sport.
