I've signed up for 2 leagues that are new to me this year. They are Yahoo! Sports Fantasy Baseball and Fox Sports Fantasy Baseball, which they are both free. Last year and several years prior I was apart of a free league through MLB.com. It was just call Fantasy Baseball 2016, but unfortunately they've discontinued the league. Between the 2 leagues, Yahoo and Fox Sports, I'd recommend the Fox Soorts league over Yahoo! The Fox league is much more user friendly. To be honest, I'm not even sure I'll keep the Yahoo team because the format is just that bad. Joining leagues with either is easy because you can join immediately and start drafting a team within 5-10 minutes.
