French Open 2025 betting tips & predictions | Day 9 preview

The fourth round of the 2025 French Open wraps up this Monday with several excellent betting prospects across tennis bookmakers. We’ve looked over the match-ups and outlined three promising punts of varying risk, most notably an $11 wager on one of the title favourites to be eliminated.

Alexander Zverev v Tallon Griekspoor

Alexander Zverev and Tallon Griekspoor have an extensive head-to-head history, with the German leading 7-2. Of these nine encounters, none have been blowouts.

Both men are big, consistent servers and know each other’s games well. Four of their last five meetings — all within the past 12 months — have gone the distance. Given seven of their last 11 sets have gone to tiebreakers as well, this clash going over 34.5 games is a no-brainer.

Novak Djokovic v Cam Norrie

Novak Djokovic has been cruising this French Open but comes up against a stiffer challenge in the round of 16 in Cam Norrie. The pair met just 10 days ago in Geneva, with Norrie pushing Djokovic to a deciding set there.

The Brit may be ranked No.81 right now, but he’s a former top-10 player and lifts for matches like this. On clay, with Djokovic yet to be put through his paces at this tournament, Norrie pinching a set is a realistic prospect.

This punt leaves room for the Brit to pull off an upset, but back Djokovic 3-1 for a $3.25 return at BetOnline if you’re after the higher payout.

Jannik Sinner v Andrey Rublev

For those chasing longer tennis odds, consider this: the last man not named Carlos Alcaraz to beat Jannik Sinner was Andrey Rublev.

That result came seemingly out of the blue when Rublev blew Sinner off the court at the 2024 Canadian Open. The Russian was in relatively poor form, Sinner was playing brilliantly, yet it all came together for Rublev on the day.

Tennis bookies are offering a whopping $11 for Rublev to win on Monday — odds that feel far too long considering the pair’s history. To be clear, Sinner will likely win this in straight sets, but an upset isn’t entirely off the table if everything clicks for a pressure-free Rublev.
