Explanation: Heat Haze had 3 or better in 5 of his last 6 races ( a couple at a mile or less) and a 4 in his last in the BC (losing by 2-12 lengths) with trouble prior to a 2 two ago...easily the fastest and most consistent horse in the race at 4-1 with 35 days rest showing the potential to improve based on his last two races.
The real question is what was up with Musical Chimes.
