Wawrinka Arrives at Estoril for Career's Final Clay Farewell

Stan Wawrinka is making his debut at the Millennium Estoril Open this week — at 41 years of age, in the final season of his professional career. The Swiss three-time Grand Slam champion faces Argentine Román Andrés Burruchaga in the first round, in what is being billed as his last ever competitive appearance on a clay court.

One Last Push on the Red Dirt

Wawrinka announced at the start of 2026 that this would be his farewell season on the ATP Tour. He encapsulated his attitude in three words: "One Last Push." His official retirement tournament is the Swiss Indoors in Basel, scheduled for late October — a fitting send-off on indoor hard court in the country that shaped him. But the road to Basel still includes one final clay chapter, and Estoril is it.

It is the first time in Wawrinka's career that he has entered this Estoril tournament. Despite having competed at the highest level for more than two decades, the Portuguese clay-court event had never appeared on his schedule. He fills that gap now, at the very end — a debut and a farewell rolled into the same appearance.

A Career Defined by Clay's Grandest Stage

Wawrinka's relationship with clay is inseparable from the crowning achievement of his career: the 2015 Roland Garros title, where he defeated the sport's very best en route to a French Open crown that few had seen coming. Alongside his victories in Melbourne (2014) and New York (2016), the Paris title completes a Grand Slam collection that places him among the most accomplished players of the modern era.

On clay specifically, Wawrinka was often at his most dangerous. His single-handed backhand — one of the most devastating shots the game has produced in recent decades — found its fullest expression on the slower surface, where there was time to load, set, and strike. Opponents knew that conceding him one loose ball near the baseline could mean an unreturnable winner down the line. The courts of Estoril represent the final stage for that weapon in competition.

His connection with Portugal also carries a nostalgic note: in 2013, Wawrinka won the Portugal Open in Oeiras, a tournament no longer held at that venue, at a moment when he was just beginning his ascent to the very top of the game. He arrives in Estoril carrying that thread of history back to the Iberian peninsula.

After Estoril: Hard Courts and Basel

From Portugal, Wawrinka transitions to hard courts for the North American summer circuit before the curtain falls at Basel. He has made clear he has no immediate plans for coaching after retiring: "I don't want to travel too much," he said earlier this year. "I want to keep things quieter, but in the long term, we'll see."

Meanwhile, clay-court action also continues this week at Kitzbühel, where a younger generation competes for a title Wawrinka himself has won previously. The contrast underlines how rare this Estoril appearance truly is — a player of his stature, adding a new tournament to his list at the very moment of departure.

For tennis fans in Switzerland and well beyond, every remaining Wawrinka match carries added weight. Estoril is a first and unmistakably a last — a debut and a farewell on the surface where he built some of his greatest moments.
