Things are heating up in the pool as the 2020 Tokyo Olympics progress, and many Team USA athletes will be in the mix for Olympics 2020 gold in the coming days. American Katie Ledecky is a huge favorite in Tuesday's women's 1,500-meter freestyle final (10:54 p.m. ET). Just over an hour before that, the five-time gold medalist will get a rematch with Ariarne Titmus in the 200 freestyle (9:41 p.m.). Ledecky had to settle for silver when Titmus surged on the final lap and edged her for 2020 Olympics gold in Sunday night's 400 freestyle.       

Other Tokyo Olympics swimming events set for Tuesday night include finals in men's 200-meter butterfly (9:49 p.m. ET) and women's 200 individual medley (10:45 p.m.) and semifinals in the men's 100-meter freestyle. Heats will run early Wednesday, including the women's 100 freestyle (6 a.m. ET), men's 200 backstroke (6:21 a.m.) and women's 200 breaststroke (6:36 a.m.). 

Among the other notable events set for Tuesday night are preliminary matches for Team USA in men's beach volleyball (8 p.m. ET) and men's volleyball (10:05 p.m). The U.S. Men's National Basketball Team will try to rebound from its surprising loss to France with an early Wednesday tip-off against Iran (12:40 a.m.).

Before you lock in any 2020 Tokyo Olympics picks or predictions, you need to see what SportsLine's Olympics expert, Mike Tierney, has to say. 

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 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. The Olympics expert saw good value in the Norwegian, who had won twice this year and was the 2019 Grand Final champion. 

"When an event is as wide open as the guys' three-in-one sport, look for a price and go with the hot hand." Tierney told SportsLine.

The 27-year-old Blummenfelt was in disbelief as he pulled away from the younger runners in the final stages to win by 11 seconds over Alex Yee for his nation's first medal in the sport. But picking a winner was nothing new for Tierney.          

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 2021 Olympics event schedule and digging down into the individual sports. He has released two CONFIDENT best bets with big plus-money payouts.

Shockingly, Tierney is fading favorite Tatjana Schoenmaker in the women's 200-meter breaststroke! The top-seeded South African set the Olympic record in the 100-meter prelims, and the 200 is her strength. She won gold in both the 100 and 200 at the 2018 Gold Coast Commonwealth Games and the World Student Games in Naples in 2019. 

But Tierney smells an upset and is picking a HUGE long-shot to take gold! This athlete has been one of the most consistent in this field over the past three years, and the emotion of being at Tokyo 2021 could put her at the top of the podium! He's also found an underdog in another swimming event who could pull off a surprise!

You ABSOLUTELY have to see who it is and check out Tierney's analysis before making any 2020 Olympics swimming picks or Tokyo 2020 predictions of your own.
