Women's Shot Put
Two-time reigning world champion Gong Lijiao of China recorded personal bests on her last two attempts, improving twice on a mark set back in May 2016, to win gold. She had the five furthest throws of the final.
Gong has two other medals from previous Olympics, however both were awarded retroactively due to anti-doping related disqualifications. This time she'll get to stand on the podium.
American Raven Saunders, fifth at the Rio Games, took silver with 19.79m.
At age 36, New Zealander Valerie Adams, a three-time Olympic and five-time world medalist competing in her fifth Games, earned bronze in 19.62m to become the first woman to win four Games medals in a single field event.

Men's High Jump
In one of the most exciting high jump competitions in Olympic history, Qatar's Mutaz Essa Barshim and Italy's Gianmarco Tamberi, who both cleared 2.37m, decided to forgo a jump-off and share the Olympic gold.
The pair tied after three misses at 2.39m, then faced with either a jump-off or sharing gold they opted for the latter.
Barshim now has an Olympic medal in every color, having took bronze in 2012 and silver in 2016.
American JuVaughn Harrison, 22, was seventh. He still has the long jump.

American Fred Kerley and Zharnel Hughes of Great Britain won the other two semifinals.
In what's bound to be one of the most astonishing results of the Tokyo Games, Italy's Marcell Jacobs clocked a personal-best 9.80 to stunningly claim the first Olympic men's 100m gold medal of the post-Usain Bolt era.
