Despite a fast track and spring-like weather, there are 15 scratches off the program (including a handful that were first or second choice on the morning line), which leaves 56 runners.

  Haven't seen the Racing Flow numbers for Thursday yet, but preliminary indications suggest off-the-pace horses had a big edge: All four sprint winners were anywhere from 3 to 8 1/2 lengths off the lead at the first-quarter call; three of five route winners - all in fields of 6 or 7 - were fourth or fifth in the early going.
