There is another great triple jump duel coming up at the world championships.

Olympic champion Caterine Ibarguen and her closest rival, 2012 Olympic champion Olga Rypakova, both qualified for Monday’s final on their first attempt.

Ibarguen beat the automatic qualifying mark of 14.20 meters by one centimeter, while Rypakova had a mark of 14.57.

Ibarguen had a winning streak of 34 competitions going when Rypakova broke it last year in Birmingham, England.

The year’s top jumper, 21-year-old Yulimar Rojas of Venezuela, also advanced with a mark of 14.52.

It was almost vintage Usain Bolt. Slow start, work your way up, and at the end look left and right before coasting first across the line in a jog.

This time it was Wayde van Niekerk winning his opening heat in the 400 meters, his first race of possibly six in as many days at the world championships. The Olympic champion crossed in 45.27 seconds, .26 ahead of Nery Brenes of Costa Rica.

Like Bolt, a rival setting off faster no longer phases him. Van Niekerk just made sure he produced some extra power on the final straight to rein in Brenes.

Van Niekerk is seeking to win gold in both the 400 and 200 meters over the next week. He is tipped by many to become the sport’s top star now that Bolt is retiring after the world championships.

Shot put qualifying is usually about doing enough to get into the final. They didn’t tell Tomas Walsh.

The New Zealander had a massive throw of 22.14 meters, which the IAAF said was the second biggest ever in the 34-year history of the event. The championship record is 22.23 meters, set by Werner Guenthor in 1987.

Joining Walsh in Sunday’s final with a first automatic qualifying mark were Olympic champion Ryan Crouser and two-time world champion David Storl of Germany.

Wayde Van Niekerk, the man seeking to succeed Usain Bolt as the sport’s best athlete, sets off for double gold at the world championships in the 400 meters.

The South African is running the first round of the 400 on Day 2 of the worlds, and hopes to cap it with gold in the 200 next Thursday in what would be his sixth race in as many days. In the 400, the defending champion will face tough competition from Isaac Makwala of Botswana and Fred Kerley of the United States.

In other morning events, the women’s heptathlon starts with Olympic champion Nafi Thiam of Belgium the favorite after breaking the 7,000-point mark earlier this season.
