The field for the $75,000 Joey P. Handicap at Monmouth Park on Saturday includes Prendimi, Visionary Ruler, and Pnutbutter Special, winners of the three sprint stakes at the meet for New Jersey-bred 3-year-olds and up. But those races were on dirt, the five-furlong Joey P. is on turf, and nobody in the group is proven over the footing. The ground won’t be a problem for Oak Bluffs, a late-running 9-year-old who is 14 for 40 on grass. He should get a good pace setup under jockey Paco Lopez, whose job it will be to make sure the old boy doesn’t drop too far back. As for Pnutbutter Special, trainer Carlos Milian is not sure how he will handle the turf course but is hopeful it will not be a problem. If he does handle the grass, there is a good chance Pnutbutter Special will win. “Every challenge I’ve put in front of this horse, he has been up to it,” Milian said. “He’s been doing good, he’s happy now, and this is a good time to try him on turf and see what happens.” Pnutbutter Special, the lone 3-year-old in the Joey P., has been getting better and better. After going 1 for 7 to begin his career, he has won three of his last four starts, including the New Jersey Breeders Handicap by 5 3/4 lengths last time out at 8-1. That he’s happy is a bonus. According to Milian, that has not always been the case. “He’s a special horse to train because he’s not a very sweet horse,” Millan said. “He wants his own territory. He’s a bossy horse, the kind you have to be careful around.” Pnutbutter Special won a maiden race at Parx by 10 1/2 lengths in his second start. He then was beaten five straight times. “Early on, he had some bad experiences in his races, and we worked hard to get him over that,” Milian explained. “Now he’s successful again.” Milian, 38, has a 20-horse stable at Parx. It’s a family operation and his staff includes cousins, nephews, and his son. Milian started out as a groom and hotwalker in his native Puerto Rico before coming to the United States as an exercise rider. He spent eight years breaking young horses before he was given an opportunity to train in 2014 at Monmouth Park. Pnutbutter Special, who figures to press or stalk the pace Saturday, is co-highweighted at 124 pounds with Oak Bluffs. Jann Hernandez, who has been aboard for all of Pnutbutter Special’s races, has the mount. Oak Bluffs was a remarkable claim by trainer Mary Eppler in 2015. After losing him for $25,000 this March at Gulfstream Park, she reclaimed him from Jorge Navarro for $20,000 out of a win two starts ago at Monmouth. In his first start back with Eppler, Oaks Bluffs rallied from eighth to finish fourth, beaten 2 1/2 lengths by the talented Extravagant Kid in the $75,000 Da Hoss Stakes at Colonial Downs. He is back with J-breds in the Joey P., and you can be sure he’ll be gobbling up ground late. Eppler first claimed Oaks Bluffs for $5,000 in November 2015. He has since won 6 of 27 starts for her, including the $200,000 Pennsylvania Governor’s Cup, and earned $355,000 for her. Prendimi, winner of the John J. Reilly Handicap in May, was entered for the main track only by trainer Luis Carvajal Jr., meaning a field of seven will start in the Joey P. if the race stays on turf as the weather forecast indicates.
