Kenny Bednarek maintained his perfect record at Grand Slam Track as he continued to dominate the men's short sprint championship.

Bednarek, the 200m runner-up at the Tokyo and Paris Olympics, completed his sweep in the 100m sprint, beating Bryan Levell and Zharnel Hughes, who had to be separated by a photo finish.

He also equalled a world-leading time by crossing the line in 9.86 seconds, also recording a personal best, 24 hours after also clinching the 200m sprint title for the third Slam in a row.

Bednarek also beat Hughes in that event, crossing the line more than half a second before the second-place finisher.

He is the only remaining undefeated athlete in the competition, and he insists the best is still yet to come this year.

"It feels amazing, I came out to perform and that's what I did," he told TNT Sports.

"This is not the best. We've still got a lot to go. We've not even peaked yet, so you're all just getting a taste."

Meanwhile, after dominating in the 400m and 400m hurdles in Miami, Sydney McLaughlin-Levrone struggled to adapt to the shorter events.

She lost her first race in nearly two years on Saturday as she was bested by defending 100m-hurdle champion Ackera Nugent, who also triumphed in the flat 100m on Sunday.

In the women's short sprint championship, Melissa Jefferson-Wooden ran a personal best to take down world champion Gabby Thomas with another blistering race in the 200m on Saturday, before completing the sweep with a win in the 100m sprint on Sunday.

"It means everything. I've been working so hard for this, and I'm just learning so many new things about myself, the way I go about training and staying disciplined when I'm not feeling my best. I'm so happy," she said.

Alison dos Santos also lost his first Slam event; having prevailed in the 400m hurdles on Saturday, he was narrowly beaten in Sunday's event, with Trevor Bassitt taking the Philadelphia Slam.

Marco Arop remained undefeated in the 800m, overcoming new challengers in reigning World Indoor Champion Josh Hoey and Olympic semi-finalist Hobbs Kessler.

However, he could not replicate that performance in the 1500m, with Josh Kerr lunging over the line just ahead of Cole Hocker. Diribe Welteji won the women's, just beating Jessica Hull over the line.

Marileidy Paulino continued her hot streak in the women's long sprints with a season-best time of 49.12 to win Saturday's 400m, before also cruising to 200m glory.

Matthew Hudson-Smith won a 400m for the first time this year on Saturday, but his up-and-down season continued as he finished fifth in Sunday's 200m, with Alexander Ogando taking the win.

Agnes Ngetich claimed a tight victory in the women's 3000m, while Nico Young claimed the title in the men's race, taking advantage of reigning champion Grant Fisher.

There is just one Slam left now, taking place in Los Angeles from June 27.
