At 11 o’clock on Wednesday morning, trainer Jamie Ness had 4,995 career wins and said he wanted to get the 5,000-win milestone over and done with in a hurry. He wrapped things up in time for dinner. After winning the second race at Parx Racing, Ness won the fifth and sixth races at both Parx and Delaware Park to earn his 5,000th victory, becoming the ninth trainer in modern American racing to do so. All five victories came in the span of two hours. “We’ve been doing this a long time,” Ness said. “It's a tough grind, man. This is a tough, tough job, but it's rewarding. The biggest reward is the horses and the people along the way, the relationships. This game has allowed me to be successful and travel to a lot of places and meet a lot of people. A lot of crazy people and a lot of great characters in this game, but I think that's what attracts a lot of people to it.” The 51-year-old trainer was at Parx when he achieved the milestone and was already on his way to the winner’s circle for his 4,999th victory after the 10-year-old gelding Bold Endeavor took a $7,500 claiming race at 3:09 p.m. Two minutes later, following a short delay involving two scratches at the gate, the 8-year-old mare Chelsea Wall crossed the line to win a starter allowance at Delaware, allowing Ness and his associates to celebrate his 5,000th career victory in two winner’s circles at the same time.  “Everybody had a good time with it because they were both [heavy favorites] in the gates at the same time, and they both came through,” Ness said. :: Access the most trusted data and information in horse racing!

Ness’s very first winner came on Aug. 21, 1999, three months after he started as a trainer, when the 3-year-old gelding Blue Rocket won a $13,000 maiden claiming race at Canterbury. Struggling at the time and considering leaving the game behind, he had to prove it to himself first.  “I remember the day I sat at Canterbury when I first started training,” Ness said. “I struggled mightily. I said, ‘I just want to win one race. I love this game, but maybe it's not for me. Maybe I'm not good. Just give me one and I'll figure out the rest of my life.’ And I got one, and then it felt pretty good.” The South Dakota native put together a tidy résumé in a nomadic start to his career, finding success at Canterbury, Tampa Bay Downs, and other tracks. But when he moved his operation to the Mid-Atlantic in 2010, starting with Delaware Park, his career exploded. In 16 seasons at Delaware since Ness began calling the track home, the trainer has won 13 training titles, including 11 straight since 2015. He has been the leading trainer at Parx each year since 2020 and has also captured multiple meet titles at Laurel Park. He has earned $110 million in purse money. In 2025, Ness won more races than any trainer in the United States and Canada with 353, beating Steve Asmussen by 22 victories with nearly 900 fewer starters. Asmussen is among the eight other trainers to have reached 5,000 career victories, along with Dale Baird, Jerry Hollendorfer, Jack Van Berg, King Leatherbury, Scott Lake, Todd Pletcher, and Bill Mott.  Ness admitted his 5,000th victory was an emotional moment, serving as an opportunity to look back on a career that wasn’t always destined for success. He didn’t wish to dwell too long, however, and the fates agreed. Twenty minutes after the trainer’s flurry to 5,000, Spikezone came home to win the seventh at Delaware, giving Ness his 5,001st victory and three-win days at both tracks. On to the next thousand. :: Want to learn more about handicapping and wagering? Check out DRF's Handicapping 101 and Wagering 101 pages.
