Can I have more than 1 team in a fantasy baseball league?

You can, but you shouldn't unless everyone else in the league is told about it. On most computer systems, you can draft two yahoo teams, as I've drafted for friends who weren't able to make the draft, and drafted two different leagues at the same time. But as for having two teams yourself it's dishonest without disclosure to other owners. Even with the disclosure, you shouldn't trade between your two teams.

If you have 2 logins and profiles you can. However, having 2 in the same league can be considered cheating by the other players. If it looks as though one team is helping the other you could have both accounts and teams frozen by Yahoo and locked out of all fantasy.

if your in a public yahoo league, then yahoo won't let you into the league twice. They check your IP and user ID. You can join a private league and theoretically have say 6 diff. ID's and create a 6 team league. That's cheating and absolutely no fun at all.

actually a 5 out of 10 could be a severe because it gets. there is the aptitude to lead the league in batting standard and you will actual lead the league in stolen bases however the shortcoming of ability is substantial which additionally ability the rbi's won't come as actual. The pitching is a extensive wildcard. Santana and Sheets are coming off of massive injuries. Harden consistently gets harm and Zambrano consistently has an "if" linked to his call.

when you join the league, it let you have an option to live draft or auto draft. if you picked live draft then i pretty sure you can draft for both of your team.

Yeah, but it is considered cheating if yahoo figures you out. Possibly other players in your league will figure you out.
