QuickTake:

University of Oregon commit Jaslene Massey completed her throws double with a silver medal in the discus, while her future teammate Mia Mireia Uusorg took second in the heptathlon at the second day of the U20 world championships at Hayward Field.

The World Athletics U20 Championships continued Thursday, Aug. 6, at Hayward Field as a pair of future Ducks showed off on the world stage. Jaslene Massey medaled in the discus, while Mia Mireia Uusorg did the same in the heptathlon. The United States swept the 100-meter titles and the 4×400-meter mixed relay. 

Here are highlights from the first two days of the meet, which continues at 10 a.m. Friday, with the decathlon.

Massey completes field double

Jaslene Massey is used to long days.

The University of Oregon commit is the reigning U.S. U20 champion in both the discus and the shot put. She’s a licensed Realtor. She was a skater, then a volleyball athlete. It makes for a busy schedule.

Thursday, after qualifying to the finals with one attempt each in both the discus (Wednesday) and shot put, she captured silver in the first with a 58.41-meter (191 feet, 7 inches) throw. She turned, moved right along and walked across the infield to the shot put ring, where she threw five times and finished eighth to complete her double.

“It’s bittersweet,” Massey said. “I’ve only been training with my coach for two years, but we created a very good platform to build on. … I’m just proud of the fact that I was able to make the transition and able to make it work and compete at the highest level of my age group.”

Uusorg wins silver in heptathlon

Oregon commit Mia Mireia Uusorg surged to the heptathlon podium on the second day of the meet. After finishing 20th in the high jump and 14th in the shot put, the Estonian was 14th overall midway through the competition. Then, though, she rattled off four straight top-three finishes — including a personal-best 2:13.90 in the final event, the 800 meters — to secure the silver medal.

“When I first failed in the high jump, I thought I was going to hate this field forever,” Uusorg said. “I don’t anymore. I love it, and I’m going to keep loving it.”

Notable U.S. winners

Tate Taylor won the men’s 100-meter in 9.94 seconds and Mia Maxwell won the women’s 100 meters in 11.14 to complete the U.S. gold-medal sweep.

The U.S. 4×400-meter mixed relay won gold Wednesday in a championship-record 3:15.31 finish ahead of a field which included five other national or area U20 record-holders.
