What's the Rule?

If Utley did miss third and was called out on a Reds' appeal, what happens to Werth's run?

PK's take: That would have been 2nd out, but what's the rule on that? Would the play have stood except Utley would be considered out? So that Werth's run counted. Or would it be considered an out and a dead ball, with Werth still on 3rd and Rollins on 1st?

At that stage, Howard's K was only out, so Utley would have been 2nd out.
Because Raul strokes a single next play, so werth's run probably scores any way you slice it. 

Why is the onus on the opposing team to appeal the missed bag? If an ump sees a player miss a bag, can he call him out?
It's the strangest custom. I mean, if a batter passes the plane on a check swing, the home plate ump can call him out. He doesn't have to wait for the catcher to appeal to the 1st base ump.

My brother's interpretation: Not sure on rule.  One possibility COULD be – werth is also out for…passing Utley on the basepaths.  If Utley doesn't touch 3rd, but werth does (in effect before Utley) then he passed him on basepaths and would be out too. I doubt that's the rule especially if it happened on appeal.  More likely is werth's run does count or he has to go back to 3rd.  I'm going to look it up. It would have changed landscape especially considering he would of scored easily because of Phillips error.

My take: Rolen says he saw Utley touch the corner of the bag, but it does point out the weirdness of the appeal rule. Just because Rolen saw it doesn't mean the ump saw it. Just to be doubly sure - and since it doesn't cost the Reds anything - and maybe the ump didn't have the angle Rolen did, why not appeal Utley's touch of 3B?
