Concerns for both apprentice jockey Reylu Gutierrez and his mount Coxswain after the latter broke down on the turn during the running of the 4th race.  The incident eliminated odds on favorite Amace, who was knocked off stride when bumped while trying to avoid the stricken horse.Jockey Edgard Zayas ultimately eased Amace who seems to be okay.  Big Boy Bruno(8-1) won the race under jockey Marco Meneses.  Will pass on additional information when available.
