Grand Slam Track: Josh Kerr wins 1500m, Melissa Jefferson-Wooden wins 100m

Great Britain’s Josh Kerr avenged his Olympic 1500m defeat by Cole Hocker in a thrilling battle in Sunday’s Grand Slam Track meet.

Hocker surged past Kerr, 27, to claim a shock victory and Olympic gold in Paris last August.

But it was Kerr’s turn to produce a decisive finish in Philadelphia, storming past the American in the final few metres to win by seven-hundredths of a second.

Kerr claimed victory in a season’s best time of three minutes 34.44 seconds.

After a fifth-placed finish in the 800m on Saturday, Kerr missed out on the top prize of $100,000 (£74,000) for the short distance group by just one point to Canada’s Marco Arop, who won the 800m.

In the women’s 100m, US sprinter Melissa Jefferson-Wooden clocked a world-leading time as she stormed to an emphatic victory.

The Olympic bronze medallist, 24, claimed victory in a personal best 10.73secs, making her the 10th fastest woman to run the distance, tied with France’s Christine Arron.

“It means everything, I’ve been working so hard for this,” said Jefferson-Wooden, who also won the 200m on Saturday. “It’s just all coming together.”

Compatriot Tamari Davis placed second in 11.03secs, with Great Britain’s Dina Asher-Smith fifth in 11.16secs.
