Here are four storylines from Day 9 of the Tokyo Olympics.
Italian Sprinter Surprises in Men's 100m Dash
Italian Lamont Marcell Jacobs was crowned fastest man in the world with a time of 9.80 in the men's 100m race. He hadn't broken 10 seconds in a 100m before 2021.
American Fred Kerley finished in second at 9.84, and Andre de Grasse was third at 9.89. All three medalists finished with new personal bests.
Qatar's Mutaz Essa Barshim and Italy's Gianmarco Tamberi decided the two would both take home gold in the high jump.
Neither had missed any of their attempts going up to 2.37 meters, but when the pair attempted 2.39, each were unsuccessful in their three attempts. Instead of continuing to see who would finally beat out the other, the two agreed they would both sit at the top of the podium.
Team USA's Raven Saunders won a silver medal in the women's shot put final on Saturday night.
The four-time NCAA champion finished with a final distance of 19.79 meters, finishing behind China's Gong Lijiao who won gold with a personal best of 20.58 meters. Saunders has become a social media sensation for her comic book-inspired masks. On Saturday night she wore a ‘Hulk’ mask for her silver-medal winning performance.
Americans Michael Cherry and Michael Norman advance to the men's 400m final. Cherry was the first member of Team USA to qualify, posting the fastest time of the evening time - 44.82 - in Heat 3. Norman closed out Heat 6, posting a time of 45.35.
Other Americans that advanced in their respective events include: Emma Coburn, Courtney Frerichs and Valerie Constien advanced to the finals in women's 3000m steeplechase, Agoura Hills' Tara Davis and Brittney Reese advanced to the finals in women's long jump, and Brooke Andersen, Gwen Berry and Deanna Price advanced to the finals in women's hammer throw.
Caeleb Dressel Wins Gold Medal No. 5
On the last night of swimming at the Tokyo Olympics, the Americans won four more medals -- setting records in two events -- to finish with 30 medals overall: 11 gold, 10 silver and nine bronze.
Caeleb Dressel won two more golds, giving him five in these Games and seven overall, while Bobby Finke picked up his second gold in the 1500m. Dressel and the rest of the men's 4x100m medley relay capped off the night in world record style, while the U.S. women picked up silver in their medley relay.
Dressel set a new Olympic record to win the gold medal in the men's 50m freestyle final on Saturday night. He also won the 100m butterfly and 100m freestyle in Tokyo. Michael Phelps and Mark Spitz are the only other male swimmers to win gold in three individual events at one Games.
Team USA's Bobby Finke won gold in the men's 1500m freestyle, while Mykhailo Romanchuk of Ukraine took silver and Florian Wellbrock of Germany took bronze.
Fellow distance swimmer Katie Ledecky congratulated him on his gold medal victories.
MyKayla Skinner Taps in for Simone Biles
After missing out on qualification earlier in the week, MyKayla Skinner will stand on the podium in vault finals. Skinner stepped in for Simone Biles after she posted the third best vault score in qualification, and she did not disappoint.
Her 14.916 earned her a silver medal in individual vault finals. Brazil's Rebeca Andrade won gold, and South Korea's Yeo Seo-jeong won bronze.
Suni Lee added yet another medal to her collection Sunday with a bronze in the uneven bars. Belgium's Nina Derwael finished in first with a score of 15.200, while ROC athlete Anastasiia Iliankova finished in second with 14.833 points.
American Hannah Roberts Claims Silver in BMX Freestyle Finals
Hannah Roberts finished second to claim the first-ever Olympic silver medal despite being a heavy favorite to win it all. She finished with 96.10 points behind Great Britain’s Charlotte Worthington, who took gold with 97.50 points.
For the men, Australia's reigning men’s world champion Logan Martin claimed gold finishing with 93.30 points.
Both Americans - Nick Bruce and Justin Dowell - finished out of medal contention. Bruce was unable to take his second turn due to injury, and Dowell fell on his second run.
