Batter interference

[DownTownTonyBrown]

I watched the final innings of the 12 inning Oakland - Bosox game late last evening (well, early morning).

Did anyone else see the batter interference call made by Marsh?

Left handed Oakland batter, called third strike (not really a questionable call, zone possibly looked a little taller than we might regularly see but seemed quite consistent). Runner stealing 2nd. Batter appeared to be slightly peaved but stepped in front of Bosox catcher and had to duck to keep from getting the ball thrown in his left ear. Marsh had already called the batter out but then he called the runner out for the batter's interference.

It doesn't seem that 6.06c is the correct rule but it seems that the runner should have just been sent back to 1st. Yes it is a live ball and the retired batter obviously interfered but the umpire basically guessed that yes the catcher and fielder were surely going to make an out. Maybe I'm just thinking of umpire interference and for interference by a retired offensive player, an additional out is required?
