When I looked at at the chart for the Kentucky Derby, I was surprised Materiality went off at $11.50/1. When I bet him I was fairly certain he had drifted up to 14/1 from 13/1 without too much time to post. Since the telecast at the facility I was watching refused to show the odds during the race (and likely that was true for all feeds), I am not sure when he was bet down. Did he get significant late action or was I just not paying close enough attention?
I noticed that also. Very late in the wagering, just before post time he went down from 14 to 11 to one. Must have been a ton of money dropped on him late.
