After more than two years of scuffling to get some traction following a solid apprentice year in 2023, jockey Luis R. Rivera, Jr., is hoping that last Sunday’s four-win day at Monmouth Park – the first four-win day of his career – will jumpstart his business.

That four-win day included a victory aboard Lost Horizon for trainer Chad Brown in the Serena’s Song Stakes. It was the first time Rivera had ridden for the five-time Eclipse Award winning conditioner and marked his first stakes win since last Nov. 1 at Aqueduct.

“It meant a lot. I think I’ve only had one three-win day before that,” said Rivera, listed to ride four races on Monmouth Park’s eight-race Saturday card, not including one MTO and one also-eligible he is named on.

Rivera picked up that stakes mount for Brown last-minute, too, replacing an injured Samuel Marin.

He enters the weekend tied for second place in the rider standings with Marin with six wins, two behind Paco Lopez.

“To be honest, I think a lot of having success as a jockey is about luck,” said Rivera, whose riding opportunities have decreased each year since he had 821 mounts as an apprentice in 2023. “I think most of the jockeys I ride with have similar abilities. You need more opportunities and you need to be on the right horse.

“I was on the right horse on Monmouth Park on Sunday when I won the Serena’s Song Stakes. But there was luck involved. I was at the right place at the right time when they needed a last-minute replacement rider.”

When he was considering returning to Monmouth Park full-time for the first time in three years, the first call the 22-year-old native of Loiza, Puerto Rico, made was to his father, Thistledown jockey mainstay Luis Rivera, Sr. (the younger Rivera’s godfather is Finger Lakes jockey Luis Perez).

“Whether I am going through tough times or good times like my four-winner day, he is the first one I call,” said Rivera, who has 249 career wins, 16 this year. “When I decided to ride all summer at Monmouth Park this year he was the first person I called to make sure it was the right move.”

As an apprentice in 2023, Rivera had solid success at Monmouth Park with 17 winners.

“I usually ride the Meadowlands at night and there are a lot of Monmouth Park people there who put me on horses, so I thought I would have some more opportunities if I came back this year,” he said. “My goal is to be in the top three in the standings. I think that’s realistic.”

The reduced riding opportunities the past three years have been particularly frustrating for Rivera, who is looking to keep more of a non-stop Paco Lopez-type schedule.

“It’s been a little tough, but after you lose your bug everything gets tougher,” he said. “Percentage-wise I am holding steady but I’m definitely riding few horses and I want that to change.

“At Aqueduct, my locker is right next to Junior Alvarado’s. Some days I’ll go there and ride one horse and win and he will turn to me and say `I want to be like you, just ride one, win and go home.’ I told him `no, I want to ride them all.’ I have the energy to do that.”

“Hopefully, with what I did last Sunday at Monmouth people will notice more. I’m ready when they do.”
