Sam P. got rank in blinkers last time....and I know Pletcher isn't a fool, I expect they will be off in the Derby.
The set of past performances I downloaded on Wednesday doesn't make note of either Sam P. or Liquidity taking the hood off....
However, the pp's on the racing forms website have them coming off.
