Pole vaulter Armand Duplantis won a fifth-successive Diamond Trophy to move within two titles of equalling Renaud Lavillenie’s record of seven.
The world record holder beat Manolo Karalis on countback after both men failed to clear 6.10m.
The United States took all the podium places in the women’s pole vault with Katie Moon finishing ahead of Sandi Morris and Emily Grove.
Switzerland’s Simon Ehammer delighted the home crowd by winning the men’s long jump with 8.32m at the Sechselautenplatz street event.
American shot putter Joe Kovacs claimed his fourth Diamond League title with 22.46m, while Canadian Sarah Mitton defended her crown with a throw of 20.67m.
Morgan Lake became the first British woman to clear two metres in the high jump at the Diamond League meeting in Zurich.
Lake sank to her knees on the mat and clasped her hands to her head after removing Katarina Johnson-Thompson's jump of 1.98m from the UK record books.
"It's still crazy, I was so in the moment and as soon as I cleared it, I was just so emotional," Lake told BBC Sport.
"This is something I’ve wanted to do my whole life and I’m so happy.
"I was a bit tired when I was warming up. But as soon as the crowd came in and the atmosphere was amazing, I was just going to go out and jump as high as I can.
"That was two metres and it shows me what I’m capable of if I believe in myself."
The 28-year-old eventually finished third behind Australia’s Nicola Olyslagers and the Ukrainian Yaroslava Mahuchikh after three unsuccessful attempts at 2.02m.
The Letzigrund Stadium will next host the finals of the remaining 26 disciplines on Thursday evening, including the 1500m, where Sarah Healy is the sole Irish competitor this week.
She comes in as the highest-ranked 1500m athlete and could become the first Diamond League champion from Ireland.
