But injury-hit Armand 'Mondo' Duplantis was forced to withdraw from the pole vault in what was the 11th meet of the 15-leg elite circuit of track and field.In what was touted as the world's best-attended one-day athletics meet at London Stadium, home to Championship football team West Ham United, Kerr was carried home by a raucous near 60,000-capacity crowd.The 28-year-old US-based Scot clocked 3min 42.66sec to smash the previous best of 3:43.13 set by Morocco's Hicham El Guerrouj in Rome in 1999.A two-time world indoor 3,000m winner, Kerr was paced to perfection by his training partner Brannon Kidder and Slovenian Zan Rudolph, and was left to punch the air in triumph as he crossed the line."It was just incredible in that last lap. It was just me, my shoes and track," said Kerr."To be honest I knew I might have it in the bag with the legs and started to glide so I was like 'I better get to the line' and to see anything with 3:42 anything was my goal so it was great."Kerr's British teammate Keely Hodgkinson, having ruled out a tilt at a world record in the 800m, got back to winning ways as she claimed victory in the two-lap race in 1:56.21 ahead of Dutchwoman Femke Broeders-Bol.Alfred continued her impressive form, the Olympic 100m champion from St Lucia bettering her own meet record from 2025 with victory in the 200m in 21.66sec.American Gabby Thomas, the 200m gold medallist from the Paris Games in 2024, had to be content with second in 21.81sec."It was most definitely a tough field," said Alfred. "It's always a pleasure and a privilege to compete against them."I am happy, I won one again."Injury concern for DuplantisAmerican Sam Kendricks was the surprise winner of the men's pole vault with a season's best of 5.95sec in a competition marked by the withdrawal of Duplantis, just three weeks out from the European championships in the English city of Birmingham."It wasn't my best day, I need to go back, reassess and maybe get a scan," said Duplantis, whose left thigh was strapped up.
