mook11 wroteMN Blue is correct (well, at least for slow-pitch)
USSSA
8.4 (g) states that the batter runner cannot touch 1b with the bat if the ball is live.
However, I do not believe there is a corresponding rule for fast pitch, although I am not an umpire...
If the batted ball has cleared the outfield fence, is not the ball now a dead ball and the batter is awarded four bases because a fair ball went into dead ball territory on the fly. Therefore, if the ball became dead before the batter touched first base, the batter is not out.
