The men’s singles field at Bastad is a little lacking in quality this year (world #16 Andrey Rublev is the top seed) but Thursday brings a compelling clash between #73 Jesper De Jong and #56 Sebastian Baez, two players who thrive on clay.

De Jong vs Baez will unfold on Centre Court circa 9:30 am ET on July 16, with a quarterfinal berth on the line.

Baez arrives as the higher-ranked player yet finds himself the betting underdog. Below, I will break down the current form, map out the betting angles, and deliver my top data-backed De Jong vs Baez predictions.

Jesper De Jong vs Sebastian Baez Picks & Predictions

Sebastian Baez Moneyline (+117 / 46¢ at Kalshi)

I am bypassing the traditional sportsbooks and heading to Kalshi for this wager. At a 46¢ contract price on the exchange, Baez translates to a highly attractive +117 payout in American odds.

The Argentinian presents. He sits comfortably ahead of De Jong in the ATP rankings (56th with 935 points vs 73rd with 808 points).

Confined to this season, the disparity is even greater: Baez is currently ranked 41st in the ATP Singles Race with 815 points, nearly doubling the season-to-date production of De Jong (87th, 458 points).

The recent clay results make the underdog price even more appealing. Baez already has a win on these Bastad courts, rallying past Markus Dahlin 4-6, 6-4, 6-1 in the opening round, and he swept five straight matches to win the Prostejov clay Challenger in June without dropping a set. That run included victories over Sascha Gueymard Wayenburg, Tristan Boyer, Maxim Mrva, Nicolas Sanchez Izquierdo, and Alex Molcan, showing that his baseline patterns are already tuned for dirt. Molcan’s overall Elo rating is 26 spots better than De Jong, and eight spots better on clay, specifically, per Tennis Abstract.

De Jong is not short on clay form himself after beating Vilius Gaubas in Bastad and making a strong push through Cattolica and Roland Garros, so I am not treating him as a soft favorite. But Baez’s long-term surface profile is stronger than this price suggests: he is 14-11 on clay in 2026, went 17-14 on clay in 2025, 25-11 in 2024, 21-12 in 2023 and 27-12 in 2022, with a massive 52-12 clay mark during his 2021 rise.

That is a much deeper clay résumé than a standard plus-money underdog usually brings.

Baez’s Elo ratings support the moneyline pick. He is ranked No. 78 overall, while De Jong is No. 101. On clay, Baez is No. 60 (1710.5), while De Jong is No. 66 (1699.6). That is not a massive clay gap, but it is another independent indicator that the plus-money underdog is slightly undervalued.

Over 22.5 Total Games (+100 / 50¢ at Kalshi)

Once again, Kalshi provides the superior payout, offering a 50¢ share that equates to +100 odds compared to the more-heavily juiced lines found at standard sportsbooks. (Kalshi also has a one-cent edge on competitor Polymarket on both this O/U pick and the Baez pick.)

The head-to-head sample is small, but it does point toward a competitive matchup: Baez won their only previous meeting (2-6, 6-3, 6-3) in the quarterfinals at M15 Monastir on hard court on Jan. 24, 2020, rallying after De Jong took the opening set.

The aforementioned Elo profiles also lean toward a tight match rather than a blowout: Baez’s 10.9-point clay Elo edge is meaningful enough to support his moneyline price, but narrow enough to suggest De Jong can keep sets competitive. Both players went well over 22.5 games in their opening matches of the tournament; De Jong hit 25 in a 7-6,. 7-5 win over Gaubas, while Baez hit 27 in a 4-6, 6-4, 6-1 win over Dahlin.

While the surface and stage are different in Bastad, the prior three-set result reinforces the idea that De Jong can make Baez work. With both players entrenched inside the world’s top 75 and bringing comparable baseline skill levels to the dirt, this sets up as a grinding, back-and-forth affair that can push past 22.5 games again.

Baez vs De Jong Odds (July 16)

Odds provided by bet365 as of July 15. Prematch betting lines are dynamic and subject to change.

The traditional betting market saddles De Jong with a -137 moneyline, carrying an implied probability of 57.8%. Baez sits as a +110 underdog, carrying an implied win rate of 47.6%. Removing the sportsbook vig to find the true market baseline reveals a vig-free probability of 54.8% for De Jong and 45.2% for Baez.

De Jong vs Baez H2H History

As mentioned, Baez leads the head-to-head 1-0 after defeating De Jong in the quarterfinals at M15 Monastir on hard court all the way back in 2020.

De Jong won the first set 6-2, but Baez responded with consecutive 6-3 sets to close out a 2-6, 6-3, 6-3 victory. With that match coming over six years ago on a different surface, it doesn’t form a huge part of today’s handicap.
