Swimming medals are still coming fast and furious, but men's golf will steal some of the spotlight in the coming days at the 2020 Tokyo Olympics. Golf was re-introduced at the Summer Games in Rio in 2016, making it part of the Olympics program for the first time since 1904. England's Justin Rose won the gold medal in the Olympic golf men's event in Rio, but Team USA Golf is stacked this year, with three of the top five players in the world.

The top three favorites in men's 2020 Olympics golf are all Americans, with William Hill Sportsbook listing recent British Open champion Collin Morikawa as the +700 top choice in its latest 2020 Tokyo Olympics golf odds. Team USA's Xander Schauffele (+900) and Justin Thomas (+1100) aren't far behind. (Head over to our 2021 Olympics page for more analysis and updates)

But there's still plenty of action in the pool, with Team USA's Caeleb Dressel the +110 favorite to win gold Wednesday in the men's 100-meter freestyle final (10:37 p.m. ET). Semifinals also will run Wednesday night in the men's 200 backstroke (10:04 p.m.), where U.S. swimmer Ryan Murphy is the +350 second favorite, and the men's 200 individual medley (11:08 p.m.), with American Michael Andrew the -137 top choice at William Hill.

Before you lock in any 2020 Tokyo Olympics picks or predictions, you really 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 2020 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 Morikawa in the men's golf event, even though he comes off a major win and is the favorite! The 24-year-old has finished in the top five in his past three events. But after his first major victory, last year's PGA Championship, Morikawa missed the cut the next week. He could ease up just a bit, and he faces stiff competition, including three teammates in the top 12 in the world.     

Tierney smells an upset brewing, and he is picking a high-value target who has a lot of incentive to win! This international athlete has the tee-to-green game to succeed at Kasumigaseki Country Club, and if he gets rolling with the putter, he could pull off an epic victory to earn gold! Tierney also has found great value in a swimming event that could bring a nice payday!

You ABSOLUTELY have to see Tierney's analysis and who he is picking before you make any 2020 Olympics golf picks or Tokyo 2020 swimming predictions of your own.

Who will win the 2020 Olympics men's golf tournament? And which high-value pick is a must-back? ... Join SportsLine now to get Mike Tierney's best bets for the Tokyo Summer Olympics, all from the renowned sportswriter who's covered nine Olympics in person and cashed big in both 2016 and '18!!
