thrown ball hits 1b coach

[bsnalex]

Had this last night, simple ground ball was thrown from F6 to F1, but F1 had glove way off line and ball pegged 1B coach. Coach went down with injury. I immediately called dead ballandawarded runners 2 bases from throw, assuming the ball would have gone dead if coach was not there ( no-one backed up the throw). BR ended on 2B, R1 ended on third.

Afterr consulting the rulebook after the game (ISF) I note 8.10.p

The runner is not out when a coach unintentionally interferes with a thrown ball or batted fair ball while in the coaches box

Only problem is, that rule is merely a classification that runner is not out and coach is not ejected. It doesn't give any effect.

Anyone know if I got this one right?
