Batter Hitting Ball while out of Box

[tibear]

Pretty sure I got the call right but just want to confirm. OBR ruleset.

For the second time in my career I called a batter out for hitting a ball while out of the batters box. Right handed batter, with R1 stealing on the pitch. Catcher is setup outside anticipating a steal. Batter steps across plate and is actually straddling home plate when he bunts the ball.

I immediately call the batter out. Defensive manager comes out looking to have runner return to first because I left R1 at second.

I checked the rule book but it doesn't say anything about calling time, dead ball, or returning runners to TOP base.

Was I correct??
