Before locking in any 2024 Summer Olympics predictions for Tuesday, July 30, 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).
