touch in the infieldfly rule

[quiggley94]

ok i know in fiels fly is a common question here but here goes:
sitc: bases full no outs B1 hits an in feild fly has to make no effort to catch touches ball but it falls to gound, IF is called batter out, runner on third goes homeon a steal stared with the pitch, runner from second makes it to third then goes home and is tagged out. play ends. pitcher appeals 3rd base runners tag up on in feild fly runner is called out. umpire based his call on the touched part of MLB defination of infeild fly rule. is that correct or is the touched not correct.
