Foul tip on pitched that bounced

[mcrowder]

Maybe it's just me....

In all other cases, we treat a foul tip the same as a missed swinging strike...

If the batter had missed, he's entitled to try to advance to first base.

Why the general assumption here that he cannot try to advance to first base, just as he'd be able to do had he missed the pitch.

Someone give me a rule reference showing where the foultip negates the ability for a batter to run on a pitch that was not caught.
