Elise Mertens is the WTA World #19 in singles and one of the most decorated doubles players in the world, a Belgian from Leuven who has won multiple Grand Slam doubles titles and established herself as a consistent, resilient presence in the singles draw across nearly a decade of professional tennis. While her doubles achievements have drawn much of the headlines, her singles ranking inside the WTA top 25 represents a sustained excellence that demands recognition on its own terms.
Mertens plays with a reliable, methodical baseline game that prioritises consistency and court positioning over outright power. She is not a player who will blow opponents off the court with flat, heavy hitting, but she is exceptionally difficult to beat because she makes very few errors and is always tactically engaged. She probes opponents’ weaknesses, adjusts her game plan mid-match, and stays competitive in close situations where players with less experience or composure tend to crack. Her serve is solid and well-placed, setting up the point construction that she prefers to outright serve winners.
Her doubles excellence has likely shaped her singles game in useful ways. Grand Slam doubles success, particularly the multiple titles she has accumulated, requires world-class net play, tactical versatility, and the ability to perform under pressure in tight moments. These skills translate to singles: Mertens is comfortable at the net for a baseline-oriented player, and she brings a calmness in important moments that is consistent with someone who has won major titles on the biggest stages.
Belgium has not historically produced a flood of Grand Slam-calibre tennis players, which makes Mertens’ longevity inside the WTA top 30 all the more notable. Kim Clijsters and Justine Henin set an extraordinarily high bar as former world number ones and Grand Slam champions, but Mertens has carved out her own respected place in the sport without anyone suggesting she is falling short of a standard set by legends. She is a reliable professional who shows up, competes hard, and delivers results, and her doubles record will be one of the standout achievements in Belgian tennis history.
Mertens will compete at the 2026 Grand Slams: the Australian Open, Roland Garros, Wimbledon, and the US Open. Check Belgium time for match schedules in her home timezone.
