Son started playing on a local travel ball team at 11 years old and also played other sports. Summer prior to 8th grade he transitioned to one of the higher level club baseball teams in the region and has done just fine. He is now a 9th grader, playing multiple sports in high school and more than holding his own in the couple of big (big for 14 year old level I suppose) tournaments he's participated in.
9U, 10U way too early to gun for that "elite" travel ball team. The couple of elite travel ball teams (which my son was not a part of - too intense) in our area disbanded once the kids hit 7th/8th grade.
Make sure he is having fun and continues to learn. In my area, there are many elite 10U and 11U players that aren't even playing baseball any more.
