Timing Play???

[rickfriedmann]

At a U13 rec game today I heard the strangest explanation of a call from an umpire I have ever heard. R3 and R1. 2 outs. BR hits a lazy grounder to 3B. R1 more walks than runs toward second. T3B throws to 2B for the force at second. Then it became interesting. PU made a point of going over to both coaches and telling them the run did not count because "it was a timing play, and the runner had not crossed home before the out at second." He THEN proceeded to say it was a timing play because R1 could have just hung out between 1B and 2B until the run scored so there was no "force" becaue BR had already reached 1B.
Are there ANY set of facts in which PU could be correct in this sitch???
p.s. - I was there watching my son play and, properly, I said not a word.
