ATP Fourth Round tips: Alcaraz eyes Paul as Slam march rolls on

Monday morning at 7:00 am AEST brings one of those Fourth Round fixtures that doubles as a clinic: world No.21 Tommy Paul squares off against Spanish powerhouse Carlos Alcaraz, ranked second and carrying an 89 per cent win rate this season. Paul arrives off a hard-fought four-set victory on 31 August; Alcaraz rolled through Yibing Wu in straight sets two days later and hasn't dropped a contest in his last five outings. The head-to-head ledger reads 6–2 in favour of the Spaniard, with their most recent meeting in January ending 7–6, 6–1, 7–5 for Alcaraz.

Paul's year-to-date record sits at 39–16, including a title, and he owns wins over quality fields when the draw opens up. His recent form tells a grittier tale: two wins and two losses across the last four starts, the latest a marathon win over an unnamed opponent that stretched to five sets. Alcaraz, meanwhile, has dropped only three matches all season (25–3) and reeled off five straight victories heading into Monday, all but one coming in straight sets. The market reflects that gulf—Alcaraz is quoted around the 1.17 mark for the match win, Paul out near 5.10—but the American has managed two wins in eight career meetings, both on hard courts, so punters hunting value will be sifting the form line for any hint of an upset yarn.

Who takes the win?

Strip the rankings away and you're still left with a chasm in 2026 form: Alcaraz has won 25 of 28, Paul 39 of 55. The Spaniard's career win percentage sits at 82 per cent across 375 matches; Paul's is 61 per cent over 398. Their last five meetings span January 2026 back to August 2023, and Alcaraz claimed all five—four in straight sets, one in five. The sole wrinkle is surface: Paul's two career wins over Alcaraz both came on hard courts (2–3 head-to-head on the surface), while the Spaniard blanked him 2–0 on clay and 1–0 on grass.

Paul's most recent outing—that five-set grind on 31 August—showed resolve but also wear; he dropped sets in the middle before closing out the decider 6–3. Before that he lost to Learner Tien in straight sets and to Kamil Majchrzak in a tight three-setter in late July. Alcaraz, coming off a clinical 6–6, 6–3 dismantling of Wu, has been near flawless. His worst wobble in the last five was a four-set win over Jaime Faria on 3 September, where he still closed the door 6–2 in the fourth. When you overlay the 6–2 career dominance—including a 7–6, 6–1, 7–5 drubbing in their last clash—it's hard to mount a case for the American on match-winner merit alone.

The win market tells the story the form already wrote: Alcaraz is overwhelming favourite, Paul the arithmetical hope. Our tennis tips lean with the weight of evidence—the Spaniard's consistency, recent run of five straight victories, and a head-to-head ledger that reads like a training diary make him the play at short odds.

Can Paul force the Sets line?

The bookmaker has hung a Sets line of 1.5, meaning Paul gets a one-and-a-half set start and Alcaraz lays the same margin. To cover, Alcaraz needs a straight-sets win; Paul collects if he nicks even a single set. The American's recent form includes that five-set thriller and a pair of straight-set losses, but he did push one opponent to tiebreaks in early August. Alcaraz, by contrast, has won four of his last five in straight sets, the lone exception a four-setter against Faria where he still dominated the final frame.

History offers Paul a sliver of encouragement: in their eight meetings he's taken at least one set in three of them, including a five-setter in July 2024 (lost 6–7, 6–4, 6–2) and a tight three-setter in August 2023 (lost 7–6, 7–3). The other five were straight-sets sweeps. Given Alcaraz's relentless 2026 form and Paul's up-and-down last month, the safer lean is on the Spaniard to roll through in three. The Sets market reflects that expectation, and we're inclined to agree.

Total Games: will it run long?

The Games total sits at 35.5, and the question is whether this match stretches into multiple tiebreaks or ends in tidy fashion. Their last five head-to-heads averaged around 30–32 games when Alcaraz won in straight sets, climbing toward 38–40 when Paul forced a fourth or fifth set. The January 2026 meeting went 7–6, 6–1, 7–5—three sets, roughly 33 games. The July 2024 five-setter tallied closer to 47 games. Alcaraz's recent run has been efficient: his last five outings averaged well under 30 games per match, with only the Faria four-setter nudging higher.

Paul's grind-it-out style can drag matches into the mid-30s or beyond when he's competitive, but his recent losses came in straight sets without much fuss. The over case hinges on Paul stealing a set and pushing Alcaraz into a tiebreak or two; the under case trusts the Spaniard's current ruthlessness. With the total pegged at 35.5, we lean under—Alcaraz in three tidy sets keeps the game count in check.
