scoring a basehit

[mikeredd]

Newbie here.... I believe this is a pretty easy question, for all leagues.
Batter hits the ball deep in the out field for an easy double. BR then tries to stretch an easy double to a triple, and is thrown out. How do you score this? I know it's an out, but some coaches are telling me that it's a scored as a hit double, but then an out at third?

What about this situation? Same scenario as above, but the BR is standing on second while the ball is being thrown back to the infield, while the ball is in the air, the BR takes off to third to try and run behind the ball, but is thrown out at third. Is that scored as a double then thown out going to third?
