Hitting the home stretch toward Tokyo

Women's world shot put champion Gong Lijiao also impressed in Shaoxing. The 32-year-old won with a throw of 20.31 meters to become the only female shot putter to surpass the 20m mark this year.

"Earlier I said my goal was to throw over 20 meters at this competition, and now I have made it. That has given me a lot of confidence for the Tokyo Olympics," said the two-time world champion.

"I believe I can achieve a better result in Tokyo. Today I didn't have a really good pace at the start, so I feel I have room for improvement. Now we have less than 40 days to go before the Olympics, so at the Games I will be stronger and hope to achieve my dream.

"It's been a while since an athlete anywhere in the world has thrown over 20 meters, which is a barrier for shot putters. Whoever can break the barrier can be more confident."
