Grass Tennis Club

Grass Tennis Club Form Book:
Grass Tournament Season, 2026

The grass-court season is the shortest and least forgiving passage of the tennis year, a precious handful of weeks in which the ball skids low, the margins shrink to almost nothing, and reputation counts for rather less than it should. As the world’s best players battle it out at the All England Club, Grass Tennis Club analyses the player form book and makes its own predictions about the winners and losers in the coming fortnight.

Grass, you will appreciate, is no respecter of status. The world rankings measure a season’s accumulated weight, patiently gathered over a year; the grass court measures something altogether more immediate. And over these past few weeks in the build-up to Wimbledon, the two have been telling rather different tales. Grass Tennis Club lays the state of play before you, much as a form book would.

Bonmont Tennis Masters

5–7 June 2026· Country Club de Bonmont, Switzerland· Three-day grass exhibition· Six top ATP men

Before the tour proper stirs into life, the grass season now has an overture, and a rather elegant one at that. Staged across three midsummer days above Lake Geneva, on what is the only grass court in all of Switzerland, the Bonmont Tennis Masters has quietly appointed itself the most civilised way to begin a grass campaign. Six of the leading men gather in an intimate, almost garden-party setting to shake the clay from their shoes and rediscover the particular footwork that the lawn, and the lawn alone, demands. It is, in the truest sense of the word, a prelude: the world’s elite, preparing for Wimbledon, in full and unhurried view.

That such a surface should exist at all is something of a small marvel, a true English lawn coaxed into being in continental Europe, where well-made grass courts remain vanishingly rare. For its third edition, six of the leading men gathered to christen the season; and it was Corentin Moutet who carried off the honours, the Frenchman standing as the only undefeated player in the round-robin format. It is a genuine pleasure to see the event take its place as the fixture that now opens the road to SW19.

Corentin Moutet, that most inventive of left-handers, rather lit up the round-robin, taking the unofficial crown by accounting for both Stan Wawrinka, the home favourite, and Arthur Rinderknech in turn. Meanwhile, the other half of the draw descended into a complete deadlock: Karen Khachanov, Alexander Bublik, and Tomás Martín Etcheverry spent three days trading victories to finish in a fiercely competitive 1-1 triangle when the grass was finally cleared.
