The back half of this week's 2021 Summer Olympics events are approaching. China leads the gold medal race with 32, but the United States is second with 25 and looks to continue building its lead in total medals (79). America's Athing Mu dominated in the 800-meter run on Tuesday and won gold. Sydney McLaughlin broke her own world record en route to gold in the 400-meter hurdles on Wednesday. The United States could secure more hardware on Thursday, and the USWNT has a chance to get the ball rolling on the pitch.

One of Thursday's earliest events will be a women's bronze medal soccer match between Australia and the United States. Caesars Sportsbook has the United States as a -137 underdog on the money line despite its goalless tie against the Opals in the group stage, while Australia is a +380 underdog. Will the result be different in the rematch?

Before making any 2020 Olympics bets, you have 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.

And for the 2018 Winter Olympics in Pyeongchang, Tierney hit two of his three predictions: Germany (+200) to win the most gold medals and the United States winning Under 10.5 gold medals (+110).

Now, with the Tokyo Summer Olympics underway, Tierney has analyzed every angle of Thursday's women's soccer matchup between Australia and the United States. Tierney is backing the Opals on the money line at +375, and he'll provide reasoning for his pick below.

He's also identified two other plus-money options for Wednesday. You ABSOLUTELY need to see what he has to say before locking in your picks.
