Veteran Jan-Lennard Struff (No. 81), boasting a career 61% clay win rate, advanced via a gritty 7-6(3), 6-0 upset over Alexandre Muller, leveraging his booming serve amid early 2026 struggles including a Monte Carlo qualifying loss. With no head-to-head history, Madrid's high-altitude clay—favoring aggressive first-strike tennis and powerful serving—bolsters Struff's upset potential against the steadier Michelsen, whose consistent form drives trader consensus toward a competitive baseline battle.
