US Open: Sakamoto vs Tiafoe Odds, Picks & Where to Watch
Thirty-eight aces changed Rei Sakamoto’s US Open from a feel-good debut into a genuine second-round threat. The 20-year-old qualifier now faces Frances Tiafoe on Wednesday, with the American returning barely 48 hours after surviving his own five-set escape. Tiafoe owns the ranking, crowd and Grand Slam experience, but Sakamoto’s fearless serving makes a routine favorite cover far from automatic. This Round of 64 matchup is less about who advances—and more about how much resistance the Japanese newcomer can sustain here.

Expert Picks: Rei Sakamoto vs Frances Tiafoe
🥇 Best Bet: Rei Sakamoto +5.5 Games
Sakamoto has earned this number after winning four matches in New York and blasting 38 aces past Aleksandar Vukic. Tiafoe needed five sets to escape Martin Damm and has not looked fully secure from the baseline. The American should advance, but Sakamoto’s serve gives him enough cheap holds to stay inside a generous game spread.

Pick 2: Over 37.5 Total Games
Both first-round matches reached a deciding fifth set, immediately putting a modest total in play. Sakamoto has produced a tiebreak in two of his past three US Open matches and rarely offers easy return games when his first serve lands. Four competitive sets should be enough, while a fifth would make the over highly likely.
Pick 3: Frances Tiafoe to Win 3-1
Tiafoe’s experience, superior return game and home-court energy should eventually break the qualifier’s resistance. A straight-sets call feels too aggressive against a server who fired 38 aces in Round 1. Sakamoto can steal an early set, but Tiafoe owns the athleticism and shot tolerance to control the match once rallies become increasingly physical and demanding.
Pick 4: A Tiebreak to Be Played
This is the market built for Sakamoto’s biggest weapon. The 6-foot-4 qualifier generated 38 aces against Vukic, while his qualifying victory over Kei Nishikori also included a second-set tiebreak. Tiafoe served unevenly against Damm, but he remains difficult to break in New York. One extended service duel could be enough to cash this prop cleanly.

Final Prediction
Sakamoto’s ranking undersells the challenge facing Tiafoe. The Japanese qualifier has found his serve, embraced the stage and demonstrated that he can survive pressure deep into a fifth set.
That should keep the opening half competitive. Tiafoe ultimately owns more ways to win. He can defend more effectively, extend rallies and attack Sakamoto’s second serve whenever the qualifier’s first-delivery percentage drops. His experience should also help him manage the important points more cleanly. Expect Sakamoto to force at least one tiebreak and grab a set before cumulative fatigue and Tiafoe’s superior movement decide the match.
