Rei Sakamoto goes for his first top-10 win, taking on Alex De Minaur, who suffered a leg injury five days ago.
Sakamoto is at +221 on the moneyline.
Current Form:
Alex De Minaur received a walkover win over Alex Molcan (undisclosed ailment) in the second round of the 2026 Shanghai Masters. The development gave De Minaur extra days to recover from the hamstring injury that forced him to retire from his championship match against Novak Djokovic at the 2026 China Open.
Rei Sakamoto barged into the second round of this ATP 1000 event after stunning Andrey Rublev 6-3, 6-3. The Japanese qualifier has now won his last four matches in Shanghai, dropping only one set so far.
The Matchup: De Minaur and Sakamoto will play against each other for the first time on the ATP Tour.

Our Alex De Minaur vs Rei Sakamoto Prediction
The Difference Maker: Alex De Minaur felt discomfort in his left leg during his final match against Novak Djokovic, forcing him to concede the match and the China Open title. It has been 5 days since that match, and yet De Minaur's team hasn’t released a statement to address the status of the injury.
What to Expect: Rei Sakamoto scores first top-10 win over De Minaur. Sakamoto’s massive serve should present a serious problem for the Aussie, especially if he hasn’t fully recovered from his injury.
Sakamoto at -115 to cover +3.5 games is already a solid deal given the situation, but 6% of bettors at DraftKings feel the Japanese has a real shot at an upset over a limping De Minaur.
Fearless Forecast: Rei Sakamoto wins 6-4, 7-6
