r/baseball (about 3.2M members, directory rank #323) focuses mainly on MLB but welcomes other leagues and levels. An MLB-branded community and a multi-sport feed are useful splits.
Stay on baseball for broad baseball discussion. Use mlb for thirty-team MLB news and highlights, and sports for multi-league sports news.
