Paris Olympic 100m finalist Oblique Seville and national record holder Nickisha Pryce have been added to the star-studded line-up for the lucrative Grand Slam Track circuit that was launched earlier this year by former world 200m and 400 metre record holder Michael Johnson.

The elite additions will compete in all four Slam events during the league’s inaugural season, starting at the National Stadium in Kingston, before moving to Miami, Philadelphia and Los Angeles.

Pryce had a strong collegiate career that culminated in her becoming the 2024 NCAA 400m Champion, breaking the NCAA record and Jamaican national record with her 48.89-second performance. She further improved her national record to 48.57 seconds at the London Diamond League and competed in the 400m semi-finals at the 2024 Summer Olympics.

“Joining Grand Slam Track is a dream come true for me,” said Pryce. “I’ve spent years working toward competing at the highest level, and this is the perfect opportunity to push myself even further. I’m excited for the challenge and ready to bring my best to every race. The road ahead will be tough, but I believe I have the strength to rise to it and accomplish even more, both on and off the track.”

Seville in 2024 clocked a world-leading 9.82 seconds at the Racers Grand Prix in Kingston and ended the season with a personal best of 9.81 seconds from the Paris Olympics, where he was a finalist.

“I’ve always known that to be the best, you have to compete with the best, and the opportunity to do that in Grand Slam Track is exactly what I’ve been preparing for,” said Seville. “The races in this series will be a perfect platform to test my speed, consistency, and ability to perform under pressure. I’m excited to show the world that I can compete at the highest level and continue breaking records. The challenge of Grand Slam Track excites me because it’s more than just about personal success—it’s about competing at the pinnacle of the sport and pushing the limits of what’s possible.”

Pryce and Seville join Jamaican compatriots Ackera Nugent, Roshawn Clarke and Rushell Clayton in the competitive field which also includes the likes of world record holder Sydney McLaughlin-Levrone, Gabby Thomas, Masai Russell, Quincy Hall, Fred Kerley and Jasmine Camacho-Quinn.

The remaining 48 competitors will be known as Grand Slam Track Challengers and will be paid a set appearance fee to compete at individual meets.

The GST Challengers are selected by the Grand Slam Track Racing Committee based on a combination of factors including recent performances and the most intriguing athletes and match-ups.
