Briton Matthew Hudson-Smith has been crowned Grand Slam Track's first champion in the men's long sprints group, as he won the 200m 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," said the Paris Olympics 400m silver medallist, who pocketed $100,000 ($A165,000) for the victory. "I'm getting to the end of my career so it's time to start saving." The new circuit is fronted by retired American sprint great Michael Johnson, with a stated 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, 400m hurdles world record holder Sydney McLaughlin-Levrone and Australia's Jessica Hull, the silver medallist in the 1500m at the Paris Olympics. Hull was fourth in the women's 1500m on Saturday in four minutes 5.48 seconds in a race won by Ethiopia's Diribe Welteji (4:04.58). A day earlier, Hull was third in the 800m in a personal best of 1:58.58. Welteji won the overall women's short distance group, with Hull in fourth spot. The three-day meet ends on Sunday.
