Tennis betting tips: US Open Day Eight Predictions for Monday

Can Day 8 of the US Open Deliver More Shocks?
  • Jannik Sinner has won 31 out of 33 hardcourt matches in 2024.
  • Tomas Machac leads the head-to-head against Jack Draper 3-0.
  • Beatriz Haddad Maia dropped only four games in her last match.

Best Bet

Bookmaker
Jannik Sinner to Win 3-0 @ 6/4
Reasoning
Sinner's dominance on hard courts and consistent form make him the favourite to win in straight sets. His powerful serve, baseline control, and Grand Slam experience should neutralise Fritz’s strengths, especially under pressure.

Day eight of the US Open promises a blend of expected outcomes and potential surprises as the competition narrows down. With the exits of major contenders such as Carlos Alcaraz and Novak Djokovic in the opening week, Jannik Sinner now stands as the top seed and is highly favoured to claim the title. The Italian has been in commanding form, dominating his previous rounds with a string of victories that underline his impressive hardcourt season record. His next challenge comes against Tommy Paul, who, despite his reputation, has struggled to find his best form in this tournament.

Elsewhere, British hopeful Jack Draper will face Czech challenger Tomas Machac. Draper, the last Briton standing, has impressed many with his form, but Machac’s resilience and the history between the two suggest this could be a closely contested battle. The women’s draw also features a compelling clash between Caroline Wozniacki, the seasoned Dane who has made a surprise run to the fourth round, and Beatriz Haddad Maia, who has been ruthless in her march through the tournament. All eyes will be on these key matches as the US Open enters its decisive stages.

US Day 8 Accumulator

Bookmaker
US Open Day 12 Double @ 15/1
Reasoning
Backing Sinner to win after losing the first set combines Draper’s strong start with Sinner’s adaptability. Meanwhile, Tiafoe thrives as the underdog, making his upset over Fritz a high-value pick.

Jannik Sinner’s current form makes him the standout player as we approach the later stages of the US Open. Since a shaky start where he dropped a set to Mackenzie McDonald, Sinner has been imperious, losing only 18 games across his next nine sets. His performance against Christopher O’Connell in the previous round was particularly notable, as he delivered 15 aces and maintained his serve without any breaks, cruising to a straight-sets victory.

Paul, in contrast, has struggled to reach his top level during the hardcourt season. His third-round performance against Gabriel Diallo was lacklustre, and he barely scraped through in four sets against a qualifier. This kind of form is concerning as he faces Sinner, who has been practically unbeatable on hard courts this year, boasting a 31-2 record. Sinner’s ability to control rallies with his powerful groundstrokes, combined with his improved serving accuracy, suggests that Paul will have a hard time breaking through.

When these two met on hard courts last year, Sinner dispatched Paul in straight sets, with Paul unable to handle Sinner’s relentless pressure. Paul’s second serve was particularly vulnerable, winning just 38% of those points, and this is likely to be an area of exploitation once again. Furthermore, Sinner’s first serve percentage in that match was relatively low, at 46%, yet he still dominated. Given his current form, it’s reasonable to expect that he will improve on that figure, making it even harder for Paul to mount any significant challenge.

Given all these factors, the best bet for this match is Sinner to win in straight sets. Paul’s current form and historical struggles against Sinner suggest a one-sided encounter, making the odds-against price for a 3-0 Sinner win highly appealing. The Italian’s dominance on hard courts, combined with Paul’s inconsistencies, points towards a straightforward victory for Sinner as he continues his march towards the title.

Additional Prediction

Bookmaker
Over 9.5 Games in the First Set @ 3/5
Reasoning
For those seeking an alternative angle, backing over 9.5 games in the opening set is a solid option. Both Sinner and Fritz have strong serves, making early breaks unlikely and increasing the chances of a tightly contested first set.

While Jack Draper has shown great promise in his run to the fourth round, Tomas Machac represents a stern test that could lead to an upset. Machac has been flying under the radar but has quietly put together an impressive series of performances. Not only has he defeated higher-ranked players like Sebastian Korda and David Goffin, but he also holds a 3-0 head-to-head record against Draper.

Their most recent encounter on clay saw Machac win in straight sets, but what’s more pertinent is their hardcourt meeting last year, where Machac emerged victorious in three sets. Draper has improved since then, but his physical durability remains a concern, especially if the match turns into a grinding battle. Machac, with his unorthodox backhand and ability to mix up the pace, could very well drag Draper into a long, exhausting match.

Machac’s recent victories over top players on hard courts, including Andrey Rublev and Frances Tiafoe, suggest he has the tools to trouble Draper. The Czech’s ability to withstand pressure and counterpunch effectively makes him a live underdog in this contest. At odds of 11/5, Machac to win is a value bet, considering his form and past success against Draper.

Additional Prediction

Bookmaker
Medvedev to Win vs Sinner @ 11/5
Reasoning
Medvedev’s defensive skills and hardcourt consistency make him favoured against Sinner, whose injuries may hinder long rallies. Medvedev’s counterpunching and experience provide strong value at 11/5 odds.

Caroline Wozniacki’s unexpected run to the fourth round has been one of the stories of the tournament, but her journey is likely to end at the hands of Beatriz Haddad Maia. The Brazilian has been in scintillating form, particularly in her demolition of Anna Kalinskaya in the previous round, where she dropped just four games. Haddad Maia’s powerful baseline game and aggressive style have been key to her success, and she seems well-equipped to handle Wozniacki’s more defensive approach.

Wozniacki, a two-time US Open runner-up, has not reached this stage since 2016, and her lack of match practice in recent years could be a factor against a player of Haddad Maia’s calibre. The Brazilian’s confidence is high after a successful summer, and her ability to dictate rallies with her heavy forehand will likely force Wozniacki into uncomfortable positions. Given the form Haddad Maia has displayed, backing her to progress at odds of 10/11 offers decent value.

Additional Prediction

Bookmaker
Draper to Win vs de Minaur @ 1/1
Reasoning
Sabalenka, in dominant form, is favoured to beat Zheng in straight sets. Zheng has struggled against Sabalenka before, and Sabalenka's powerful serve and baseline play should secure her victory.

Jordan Thompson has been playing some of the best tennis of his career, and he looks capable of upsetting his fellow Australian, Alex de Minaur. De Minaur, despite a strong showing against Dan Evans, has admitted that he’s not fully recovered from a hip injury. This admission, coupled with the fact that Thompson’s game is built around frustrating opponents with his defensive skills and clever slices, suggests that this could be a tough match for de Minaur.

Thompson’s form has been solid, and he has a knack for pushing higher-ranked players to their limits. De Minaur’s aggressive style may not pay off as well against Thompson, who is adept at absorbing pressure and countering effectively. With de Minaur potentially not at 100%, Thompson has a genuine chance of causing an upset, especially given the odds of 27/10, making this a worthwhile outside bet.
