However, Herbert leads their head-to-head 1-0, defeating Den Ouden 3-6, 6-3, 6-2 in Australian Open qualifying in January on hard courts, and brings superior clay experience as a former top-40 player with strong net skills honed in last week's Barcelona doubles final. Both have limited clay success in 2026—Den Ouden 0-4, Herbert coming off a Marrakech qualifying loss—highlighting a competitive matchup where surface adaptation, stamina in best-of-three sets, and weather could sway implied probabilities amid no reported injuries.
