Both Joma players have added a new Grand Slam title to their careers after claiming the doubles crown at Roland Garros 2026.
Joma players Marcel Granollers and Katerina Siniakova have been crowned champions of Roland Garros 2026 in the doubles category, once again taking the brand to the top of one of the most important tournaments on the international calendar.
As the official technical sponsor of both players, we celebrate this double achievement with immense pride. Both athletes have demonstrated their potential on court, taking Joma to the very top of world tennis.
Marcel Granollers relives his dream
Granollers has once again lifted the trophy in Paris alongside Horacio Zeballos for the second consecutive year, confirming his outstanding form in doubles and continuing an already historic Grand Slam journey. After winning his first Roland Garros title last year, marking a turning point in his career, the Spanish player returned this time to defend his crown with the same determination.
This new milestone reflects a career built on consistency and experience: 12 ATP 250 titles, six ATP 500 titles, 10 Masters 1000 titles, the ATP Finals, and three Grand Slam titles (Roland Garros 2025, US Open 2025 and Roland Garros 2026). Winning again in Paris has confirmed his status as one of the leading figures in world doubles tennis.
Fourth Roland Garros title for Katerina Siniakova
Siniakova also shone in the women’s doubles draw, where she claimed the title alongside Taylor Townsend. The current world No. 1 in doubles added another success on clay, maintaining her position among the leading names in international tennis.
Her 2026 season has been marked by highly valuable titles. Since joining Joma, the player has claimed victories at WTA 1000 events (Mutua Madrid Open, Miami and Indian Wells in 2026), the Dubai WTA 500, and two Grand Slam titles: the 2025 Australian Open and now Roland Garros.
Roland shoes: competing with elite-level performance
Throughout the tournament, both players wore Joma apparel and competed in the Roland model, a high-performance shoe developed to meet the demands of elite tennis. Tested at the J Lab innovation centre, these shoes combine support and cushioning, enabling fast and explosive movement in every match.
- Double-density technical phylon midsole, featuring a lighter layer to soften impacts and provide a comfortable stride, combined with a firmer layer that reinforces midfoot support and ensures control during quick movements.
- Stabilis system integrated into the midfoot area to provide additional support during lateral movements and help prevent injuries.
- Enhanced ventilation thanks to the VTS system located in the upper, facilitating sweat evacuation and helping regulate moisture.
Two champions, two doubles titles and one brand on court. Roland Garros 2026 leaves a clear image for Joma: technical product competing at the highest level on one of the most demanding stages in tennis.
