Does run count

[rbmartin]

4.09 HOW A TEAM SCORES.
(a) One run shall be scored each time a runner legally advances to and touches first, second, third and home base before three men are put out to end the inning.
EXCEPTION: A run is not scored if the runner advances to home base during a play in which the third out is made
(1) by the batter runner before he touches first base; (2) by any runner being forced out; or
(3) by a preceding runner who is declared out because he failed to touch one of the bases.

None of these exceptions apply in this situation



7.10 Any runner shall be called out, on appeal, when-(a) After a fly ball is caught, he fails to retouch his original base before he or his original base is tagged; "Retouch," in this rule, means to tag up and start from a contact with the base after the ball is caught. A runner is not permitted to take a flying start from a position in back of his base.


Verdict....If runner touches plate before throw (appeal throw) arrives at 2nd and barring an appeal on another runner....score him.
