DEL MAR, Calif. – Victor Espinoza was supposed to be riding Accelerate in the Grade 1, $1 million Pacific Classic on Saturday at Del Mar, but instead he’s forced to be an interested observer, watching the meet’s championship race while continuing to recuperate from a nasty accident nearly four weeks ago. Espinoza fractured the transverse process of his C-3 vertebra, putting him indefinitely on the sidelines.

“The hardest thing I’ve been through,” Espinoza said recently at his home just east of the track.

Trainer Jorge Navarro is dominating Monmouth Park like never before. Through Sunday, he has 63 wins during the first 38 days of the season. With 14 dates remaining, he is only two shy of the record he set in 2017, which was six more than the record of 59 he established in 2016.

Navarro has won three or more races in a day eight times this Monmouth meet. A year ago, he only had five days with three or more winners. On July 23, 2017, he tied a Monmouth record held by Todd Pletcher when he won five races on a card. He has tied that mark twice so far in 2018.

Baffert said he would also run Roman Rosso, but that Mubtaahij would not run.

Eight were expected to be entered: Accelerate, Beach View, Dr. Dorr, Pavel, Prime Attraction, Roman Rosso, The Lieutenant, and Two Thirty Five.
