Kenny Bednarek set a world-leading time of 19.84 seconds to claim the men's short sprint championship on the final day of Grand Slam Track in Miami on Sunday. 

Bednarek, the 200m runner-up at the Tokyo and Paris Olympics, won across the same distance on Sunday, beating Zharnel Hughes and Oblique Seville. 

The American captured the Miami men's 100m title 24 hours earlier with a time of 9.79 seconds, leading from Seville and Ackeem Blake. 

Bednarek is one of only three athletes to have won every race they have competed in, and he showed no signs of slowing down ahead of the Philadelphia Slam later this month. 

"I'm going to be dominant this year," said the 26-year-old twice Olympic silver medallist, who is $200,000 richer with his wins in Miami and Kingston. "I'm right where I need to be."

Sydney McLaughlin-Levrone also maintained her perfect start with victories in the 400m and 400m hurdles over the weekend. 

Four-time Olympic gold medallist McLaughlin-Levrone ran a world-leading 52.07 in the hurdles race before season's best of 49.69 in the flat race on Sunday. 

She has now won 12 consecutive 400m hurdles finals dating to her last defeat at the 2019 World Championships, breaking the world record six times in that span. 

Brazil's Alison dos Santos won the 400m in 44.53, a personal best by one hundredth, to also sweep the men's 400m-400m hurdles group. 

Melissa Jefferson-Wooden, meanwhile, also won her second Grand Slam Track title, clinching the women's short sprints group. 

Jefferson-Wooden won Friday's 100m and took third in Saturday's 200m in a personal-best 22.15 seconds for 18 total points to lead the overall standings by five points. 

The Olympic bronze medallist edged out her Paris relay teammate Gabby Thomas, who ran a season's best 21.95 seconds in the 100m. 

Tamari Davis finished second in both of the short sprints, recording a personal best time of 22.05 in the 200m, where Jefferson-Wooden finished third. 

Favour Ofili claimed third place in the 100m, and ran a season-best 22.27 in the 200m, but could only manage a fourth-placed finish. 

10.75. Wind or not, she’s unstoppable.

In the men's short distance category, Britain's Josh Kerr claimed his first Grand Slam Track title after winning the 1500m on Friday in a season-best time of 3:34:51. 

The world 1500m champion finished fifth in Saturday's 800m in a personal-best 1:45.01 for 16 points, two points clear of Canadian Marco Arop.

Kerr finished level on 16 points with American Yared Nuguse after their performances in the 800m, but the Scot took the overall win based on having the highest individual finish.

"These are going to be awesome shows that we're doing," said Kerr. "If I keep progressing the way I am, then I can come away with two more slams this year. 
In the men's long sprints, Jereem Richards led the way after picking up 20 points, finishing first in the 200m before a second-placed finish in the 400m. 

Richards set a world-leading time of 19.86 in the 200m. Matthew Hudson-Smith finished seventh and third in his races to pick up just eight points. 

Grant Fisher, who picked up a pair of bronze medals in Paris, added to the home crowd's joy as he clinched the men's long distance group with 20 points.

After finishing third in Friday's 3,000m, he won the 5,000m in a time of 13:40.32, leading the Miami table from Andrew Coscoran and compatriot, Cooper Teare. 

Dribe Welteji was unable to build on her win in Kingston, finishing fourth overall in the women's short distance category as Freweyni Hailu led the way with 18 points. 

There are two more three-day slams after Miami - in Philadelphia from 30 May and Los Angeles from 27 June.
