Team USA Swimming will hold the spotlight for one more night Saturday at the 2020 Tokyo Olympics, just hours before a pair of Americans chase glory in track's most prestigious event. Team USA swimmer Caeleb Dressel will be going for his fourth gold medal of these Summer Games when he goes off as the -450 favorite (risk $450 to win $100) at William Hill Sportsbook for Saturday's 50-meter freestyle final (9:30 p.m. ET). The Team USA men will close out the Olympics 2020 swimming program by going for its 16th gold medal in as many tries in the men's 4x100 medley relay (10:36 p.m. ET), and they are favored to do just that.

Americans Trayvon Bromell and Ronnie Baker are the favorites to win Olympics 2020 gold Sunday morning in the men's 100 meters (8:50 a.m. ET). The final round of men's golf (6:30 p.m. ET) and the men's tennis gold-medal match (3:15 a.m. ET) are among the other notable events starting late on Saturday or early Sunday. Meanwhile, women's gymnastics individual medal events start Sunday with the vault (4:45 a.m. ET) and uneven bars (6:27 a.m. ET). Before locking in any 2020 Tokyo Olympics picks or predictions for those events or others, you need to see what SportsLine Olympics expert Mike Tierney is saying.

A national sportswriter whose work appears in The New York Times and Los Angeles Times, Tierney has covered nine Olympic Games in person. In the past two Olympic Games, his advice helped those who followed him cash in big, and he already has nailed a huge winner at Tokyo 2020.

Before Sunday's men's triathlon, Tierney tabbed Norway's Kristian Blummenfelt as his choice to win gold, and that bet paid off big at +600.   

At the Pyeongchang Winter Olympics in 2018, he nailed Suzanne Schulting (+2500) of the Netherlands and Norway's Havard Lorentzen (+800) to triumph in speed skating and the USA's Mikaela Shiffrin (+185) to win the giant slalom. Tierney also took the under (10.5) on the Americans' gold-medal count, and that also cashed as the USA came in with nine.

And at the Rio 2016 Summer Games, Tierney told readers to bet over on Team USA's gold medal count (41.5) and over on Team USA's overall medal count (102.5). The result? 46 golds, 121 medals and two easy cashes. Anyone who followed Tierney's advice cashed in huge.

Now, Tierney has been studying the 2020 Tokyo Olympics event schedule and digging down into the individual sports. He has released three confident Olympic best bets for Saturday, and two of them have big plus-money payouts. He's sharing those 2020 Olympics picks only at SportsLine.

Top 2020 Tokyo Olympics predictions

One shocker: Tierney is fading American Michael Norman, who is the -137 favorite in the men's 400 meters, which has heats starting Saturday at 9:45 p.m. ET. The 23-year-old has drawn comparisons to the legendary Michael Johnson, but the former USC star doesn't have a lot of global competition under his belt. He struggled with an injury at his only major senior competition in 2019, when he competed in the World Championships but finished last in his semifinal .

He ran 45.94 in that race after posting 43.45 just a few months before that, which is tied for the fourth-fastest time in history. He hit 44.07 in June's Olympic Trials, so he has the speed. But he also will be facing pressure in his first Olympic Games. His mother is Japanese, and there are high expectations. "Competing in Japan lifts his motivation but heightens the pressure in a nation that regards him as a celebrity," Tierney tells SportsLine, and the expert is taking another option.

In addition to calling for a surprise in the men's 400 meters, Tierney has locked in two other best bets for upcoming Olympic action. Two of these picks bring big plus-money payouts, so head to SportsLine and check out what Tierney has to say.
