Armand Duplantis dominates pole vault at Diamond League in China

Armand Duplantis dominated the pole vault but was unable to improve his world record and American Cordell Tinch became the fourth fastest high hurdler of all time at the Shanghai-Keqiao Diamond League on Saturday.

Olympic and world champion Duplantis soared 6.11 meters to win the competition comfortably from Greek Emmanouil Karalis (6.01) but failed in his single attempt at 6.28, a centimeter higher than the record he set in February.

"The jump did not feel that great, and the run did not feel that great either," the Swede said.

"[But] to have a good attempt while not feeling my best is actually a really good thing."

Tinch, who beat 110m hurdles world record holder Grant Holloway in the series opener in Xiamen last week, smashed Liu Xiang's meeting record with a scorching run of 12.87 seconds to match the best effort Dayron Robles managed in his career.

"It sounds pretty good," Tinch said of standing behind only compatriots Aries Merritt, Holloway and Devon Allen in the all-time list.

"I felt like I was going to run something fast (but) I didn't know it would be 12.8 fast."

American Chase Jackson, who will go for a third straight world title in Tokyo in September, won the shot put with a throw of 20.54m.

Canadian shot put star Sarah Mitton finished fourth, with a best throw of 19.59m.

It marked a slight improvement upon her performance at the Diamond League season opener in Xiamen where Mitton finished fifth (19.23m).

Mitton, of Brooklyn, N.S., won her second consecutive world indoor title in Nanjing, China, on March 21 with a throw of 20.48m.

South African Akani Simbine backed up his win in Xiamen last week by running down Olympic silver medallist Kishane Thompson in the last few strides to win the 100m in 9.98 seconds.
