Olympics 2021 live updates: There's a new fastest man alive, Caeleb Dressel caps historic week, Xander Schauffele wins golf gold

Day 9 in Tokyo marked the final visit to what has been a lucrative location for Team USA at these Olympic Games: the pool. There was also Xander Schauffele winning America's first gold medal in golf in 121 years. Then, Day 10 got underway with men's and women's gymnastics event finals. Two American gymnasts found the podium, with newly minted all-around champion Sunisa Lee taking bronze in the uneven bars and MyKayla Skinner -- who stepped in to compete when Simone Biles withdrew -- earning a silver medal in the vault.

Then, a new fastest man alive was crowned as Italy's Lamont Marcell Jacobs put on a show in the men's 100-meter final -- becoming not only the first Italian man to win gold in the event, but the first to medal in it.

But first, back to the pool, where Team USA had a spectacular last day. Caeleb Dressel started it by swimming an Olympic-record 21.07 seconds to take gold in the 50-meter freestyle. As soon as he took off from the diving board, there was no looking back for the sprint star.

Right after, Bobby Finke, who sprinted the last 50 meters to win the 800-meter freestyle, came out and did exactly the same in the 1,500-meter freestyle. He hovered in fourth place before he bolted late for his second long-distance gold -- becoming the first American swimmer in 37 years to win the 1,500-meter freestyle event.

The brilliant day for Team USA continued with the women's 4x100 relay team throwing down a nearly perfect race. Regan Smith, Lydia Jacoby, Torri Huske and Abbey Weitzeil missed the gold by 0.013 seconds, finishing second to Australia.

The last race of the day was the men's 4x100-meter medley relay -- an event the U.S. has never lost. Swimming in Lane 1, Ryan Murphy started with the backstroke, followed by Michael Andrew in the breaststroke, Dressel in the butterfly and Zach Apple finishing the race strong in the freestyle.

Team USA's quartet clocked a world-record time of 3:26:78 to win the gold.

Here's what you might have missed from a jam-packed weekend of Olympic action:

Marcell Jacobs is the fastest man alive

Remember the name. Lamont Marcell Jacobs made history on Sunday as the first Italian man to medal in the men's 100-meter final. But rather than settle for a spot on the podium, Marcell Jacobs went ahead and earned gold with a time of 9.80 seconds.

Marcell Jacobs celebrated the joyous moment with fellow Italian -- and fellow gold medalist -- high jumper Gianmarco Tamberi.

It was an American, Fred Kerley, who claimed the silver medal with a personal best of 9.84.

Kerley shocked many earlier this year when he announced that he would focus on the 100-meter and 200-meter sprints and away from the 400. For anyone who still has questions about the decision, his new hardware would like a word.

What, like it's hard?

Spoiler: It is. Venezuela's Yulimar Rojas didn't just come to claim gold in the women's triple jump, she came to smash the world record with an incredible jump of 15.67 meters.

You get a gold, you get a gold ...

In an Olympic Games full of meaningful moments, it's hard not to feel like this one has to be in consideration for the most moving of them all. Italy's Gianmarco Tamberi and Qatar's Mutaz Essa Barshim decided to share the gold medal in the men's high jump rather than competing in a jump off after both athletes cleared 2.37 meters.

Let's go fast

The men's 100-meter heats started Sunday morning. Speed was expected, speed was delivered.

Schauffele finds gold on the greens

American Xander Schauffele has never won a golf major. Now, he's one of two men's golfers alive who can put a gold medal around his neck. Schauffele finished in the top 10 at all four majors in his young career, but finishing atop the leaderboard at the end of a major weekend has eluded him. Now he has the most precious of Olympic medals, five years after Justin Rose of Great Britain won it in 2016 at the Rio Games, where the sport returned to the Olympics for the first time in over 100 years.

Schauffele, 27, carded a 4-under 67 in Sunday's final round to finish 18 under par for the tournament.

All hail King Caeleb

Caeleb Dressel finished off his individual Olympics run in perfect fashion, winning the 50-meter freestyle in the last session of swimming with an Olympic-record 21.07 seconds. France's Florent Manaudou finished second, and Brazil's Bruno Fratus picked up bronze.

Historic finish for Finke

Bobby Finke has another gear. After sprinting to the finish line in the 800-meter freestyle, Finke repeated the same in the 1,500 meters. He sprinted for his second individual Olympic gold medal, recording the second-fastest time in U.S. swimming history in 14:39:65. Ukraine's Mykhailo Romanchuk finished second, and Germany's Florian Wellbrock took third.

"It means the world to me. I was just trying to hold on and try to get the hand on the wall," Finke said.

In the 800-meter freestyle, Finke shaved 5.71 seconds off his personal best in 2021 to break an American record and win the Olympic gold. In the 1,500-meter free, he took 9.05 seconds off his personal best in 2021 to win the gold. With Finke's win, the United States won gold medals in both the men's and women's 1,500-meter freestyle events.

This was the first win for Team USA in the men's 1,500-meter freestyle in 37 years.

Carrying on a golden tradition

Team USA's Ryan Murphy, Michael Andrew, Caeleb Dressel and Zach Apple swam a world-record pace to win the 4x100-meter medley relay in 3:26:78. This is a race the U.S. has never lost. Great Britain grabbed silver, followed by Italy.

Silver for Saunders

With a throw of 64 feet, 11.25 inches (19.79 meters), 25-year-old American Raven Saunders earned a silver medal in the shot put.

Australia's McKeon sets Olympic record

Australia's Emma McKeon continued to flourish in Tokyo, winning the women's 50-meter freestyle with an Olympic-record swim of 23.81 seconds. It was her sixth Olympic medal in Tokyo, her third gold. Sweden's Sarah Sjรถstrรถm finished second, and Denmark's Pernille Blume picked up bronze.

Australia took the gold in the women's 4x100-meter relay on the final day of swimming in Tokyo. USA's Regan Smith, Lydia Jacoby, Torri Huske and Abbey Weitzeil finished in second place -- just 0.013 seconds behind the gold medalists.

USA and Australia were neck and neck for most of the race. Australia finished with an Olympic-record 3:51:60. Canada picked up bronze. Australia's McKeon, who was a part of the relay race, won her second gold of the night -- and seventh Olympic medal overall in Tokyo.

McKeon is only the second woman to win seven medals at a single Olympics, tying a record set in 1952, and now has the most Olympic medals of any Australian Olympian.
