Nope, no controversy, just a bad call, it happens all the time. Controversy was whether or not the Rockies should have been awarded a HR in the seventh instead of a double.
Trevor Hoffman, ace reliever, blew this one - gave up double, double, triple and sac fly in the 13th with a 2 run lead.
And in the end - the game would at least have gone on to 14 innings as it was tied, and the Rockies still had 1 out left with a man on too. Never know how it would have come out.
