Matthew Hudson-Smith was crowned Grand Slam Track's first-ever Grand Slam champion in the men's long sprints group as he won the 200 metres on day two of the novel circuit's debut meet in Kingston, Jamaica.
Hudson-Smith was second in the standings after Friday's 400m and he won the group outright with a total of 20 points after reeling in the field in the back half of the shorter distance on Saturday, crossing the line in 20.77 seconds.
"Great to get the first one, I'm really excited and grateful," the Paris 400m silver medalist said in televised remarks, as he leaves Kingston $100,000 (£77,580) richer.
"I'm getting to the end of my career so it's time to start saving," the 30-year-old said.
American Kenny Bednarek, a twice Olympic champion, built up an enormous lead around the turn and stumbled through the tape to win the 200m in 20.07, three-tenths of a second ahead of Briton Zharnel Hughes, and clinch the men's short sprints slam.
He won Friday's 100m as well, for a point total of 24.
The new circuit fronted by retired American sprinter Michael Johnson, a four-time Olympic gold medalist, off its first of four meets this week with an aim of making Grand Slam Track the "Formula One of athlete racing."
Athletes in 12 groups - men's and women's short sprints, long sprints, short hurdles, long hurdles, short distance and long distance - compete over two races per meet with the point totals from those runs determining the champion of each group.
The start-up's super-sized purses have lured some of the sport's top competitors, including 200m Olympic champion Gabby Thomas and 400m hurdles world record holder Sydney McLaughlin-Levrone, who each notched wins on the meet's opening day.
