Before locking in any 2024 Summer Olympics predictions for Wednesday, July 31, you need to see what SportsLine Olympic insider 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. At 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. Then, at 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, Tierney has broken down the 2024 Paris Olympics from every possible angle and locked in his best predictions and bets for Wednesday, July 31. We can tell you that Tierney is backing Kristof Milak of Hungary in the men's 200-meter butterfly event.
