The 28-year-old American ranks around No. 15-20, bringing superior recent form, athleticism, and baseline power suited to the faster outdoor hard courts. Marin Cilic, at No. 85 and age 37, arrives after a first-round win over Sho Shimabukuro and his 600th career victory earlier in the season, yet his 13-13 mark and history of early exits at majors limit upside. Historical head-to-head favors the Croatian 2-0, though those encounters predate both players’ current trajectories. No major injury concerns appear for either, with Tiafoe’s overall consistency and ranking edge shaping the strong trader consensus around his advancement.
