The assembled field was outstanding in Poland. Of the 260 athletes appearing in Silesia, 55 were Olympic medallists, 101 have made the podium at world championships, and 68 were European championships medallists.Quality shone throughout the meet, in front of 40,000 spectators at the Stadion Slaski, none less so than when Jamaica's Seville blasted to a meet record of 9.83 seconds for victory.Americans Kenny Bednarek (9.87) and Christian Coleman (9.93) completed the podium.The women's blue riband event was won by their teammate Jefferson-Wooden, in the season's first head-to-head over 100m with Olympic champion Julien Alfred, in a season's best of 10.78sec.Alfred, of St Lucia, came in second, at 0.05sec."Julien pushed me, but before the race my coach told me to just control the race and focus on my own lane. I did that, did not panic, I think I did a good job," said Jefferson-Wooden.Duplantis had an uncharacteristic three failures in the pole vault, before girding himself for the business end of the showdown with Greek rival Emmanouil Karalis.The US-born Swede eventually claimed victory with a best of 6.20m, 20cm higher than Karalis. One attempt at what would have been a 16th world record, at 6.32m, was enough before Duplantis called it a day."The competition was super difficult for me. I was really sloppy at the beginning," said Duplantis."I lost a lot too much energy at those lower heights to break the world record today."Dos Santos on fire
