Jamie Ness hits 5,000th training win in rapid-fire milestone at Delaware Park

Jamie Ness reached 5,000 career training victories in a blur of back-to-back racing action, with his 4,999th winner landing at Parx Racing and his milestone horse, Chelsea Wall, delivering the decisive score in Delaware Park’s Race 6.

Chelsea Wall won the 4-horse, $25,000 starter optional claimer by 3 1/2 lengths with Paco Lopez aboard, giving Ness a milestone that was less a ceremony than a sprint across circuits. The result put him in rare company as only the ninth North American Thoroughbred trainer to reach 5,000 wins, a benchmark that says as much about durability and placement as it does about sheer volume.

The Delaware Park victory fit the shape of Ness’s current operation. He entered the day leading the track standings, and last year he claimed his 11th consecutive and 13th overall leading trainer title at the meet. Delaware’s 2026 meet opened May 13, and through May 20 Ness had seven wins from 11 starters there, a clear sign that the barn is still firing at a high rate rather than simply collecting career totals.

His climb to 5,000 has been built over decades and across multiple circuits. Ness won his first race at Canterbury Park in 1999, reached 1,000 at Presque Isle Downs in 2010, 2,000 at Laurel Park in 2013, 3,000 at Parx Racing in 2020 and 4,000 at Laurel on July 16, 2023, with Sing Scat. The path matters because it shows an accumulation of wins at places where consistency, claiming judgment and owner trust drive the business every day.

Equibase’s trainer profile showed Ness with 20,037 career starts, 4,984 wins, 3,636 seconds, 3,007 thirds and $110,017,105 in earnings before the milestone was crossed. His 2026 line was already strong, with 383 starts, 87 wins, 71 seconds, 70 thirds and $2,759,778 in earnings. The names ahead of him on the all-time North American wins list are Steve Asmussen, Dale Baird, Jerry Hollendorfer, Jack Van Berg, King Leatherbury, Scott Lake, Todd Pletcher and Bill Mott.

Ness, a South Dakota native and South Dakota State University graduate, started his training career while working in the media relations department at Canterbury Park. That background makes the milestone even more striking: he built a top-level barn through the grind of the claiming game and steady regional success, and Delaware Park is where that staying power now sits on full display.
