The Opening Ceremony of the pandemic-delayed 2020 Summer Olympics takes place on Friday at the Olympic Stadium in Tokyo, and the United States will aim to top the 121 medals it won in 2016 in Rio de Janeiro, a record for a U.S. team in a non-boycotted Games. For this year, William Hill Sportsbook has set the Over/Under for total medals won by Team USA at 111.5. Before locking in any Tokyo Olympics 2020 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. For Rio in 2016, Tierney profited big-time. He 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.
