Pole vault world record holder Armand 'Mondo' Duplantis will aim to win a fifth successive Diamond League title on Wednesday in Zurich, the Swiss city hosting the circuit's finals just two weeks before the world championships in Tokyo. "I have to be focused, I can't slack," said the US-born Swede, who has been in electric form, setting a 13th world record, of 6.29 meters, in Budapest earlier this month. "High expectations are better than no expectations. It's a good problem, honestly," he said of the public's perception of the current state of the pole vault competition. "It's bringing people to watch us, jumping high." Asked whether the 6.30-meter barrier could soon be breached, Duplantis played a straight bat. "I try to maximize my days as much as I can. And if I feel like that on the day, it's a day that I have the possibility to break the world record, I'll go after it. It would be amazing to do it here, it'd probably even more amazing to do it in Tokyo. "It really is just a beautiful circus act that we do and I think we can entertain anyone anywhere in the world." Duplantis will compete in one of six field disciplines held at a street event on Zurich's Sechselautenplatz, directly in front of the city's iconic opera house. Olympic champion Yaroslava Mahuchikh will resume her rivalry with Australia's Nicola Olyslagers in the women's high jump while there is also the men's long jump, the women's pole vault, and the shot put for both male and female throwers. "I'm ready to jump!" said Mahuchikh, the Ukrainian who set a world record of 2.10 meters last year. "I started my season very well. The main thing now is to get in shape for Tokyo," she added in reference to the September 13-21 worlds in the Japanese capital. "It's exciting, it's the main competition of the season. I'm going to Tokyo to protect my title." The remaining 26 Diamond League champions will be crowned in the course of a bumper program at the Letzigrund Stadium on Thursday. The array of global stars on show includes the likes of Olympic 100m and 200 meters champions Noah Lyles and Letsile Tebogo. They face off in the men's 200 meters, with Botswana's Tebogo hunting a first ever Diamond League title and U.S. sprinter Lyles looking to win the trophy for a record-breaking sixth time. "With Weltklasse Zurich being the last race before the world championships, I am looking to run something special," said Lyles, who had to be happy with 200 meters bronze at the Paris Olympics in a race won by Tebogo. Olympic and Diamond League champion Julien Alfred also lines up in the women's 100 meters, while 800 meters star Emmanuel Wanyonyi and 400 meters hurdles ace Femke Bol will also be looking to defend their series titles. The majority of athletes have qualified for the Diamond League finals thanks to points accrued in the 14 meets to date, while a handful will compete in Zurich on global or national wildcards. There is, however, no place for Jakob Ingebrigtsen in the men's 1,500 meters. The Norwegian, who has struggled with an achilles injury since winning double world indoor golds in Nanjing in March, was refused a wildcard because rules stipulate that he must have competed in at least one Diamond League meet during the outdoor season. He instead heads to a training camp in the Japanese city of Kyoto ahead of Tokyo to fine-tune preparation for a tilt at a 1,500-5,000 meters double.
