Quick Take

Pre-match view

Context last updated 14 Jun 2026, 08:11 · Europe/Bucharest

Wong's career-high ranking, recent title, and 3-1 H2H edge make him the favorite, but Harris's home wildcard and grass experience should keep it close.

Expect a serve-dominated match with over 22.5 games and at least one tiebreak. Best value is Wong 2-1 at 4.25, while Harris 2-0 is a clear avoid.
