World No. 1 Jannik Sinner marked his return to competitive tennis with a hard-fought victory in his opening match at the Terra Wortmann Open in Halle, Germany, on Tuesday, June 17, just over a week after his agonizing defeat to Carlos Alcaraz in the French Open final. The 23-year-old Italian defeated Tallon Griekspoor of the Netherlands 6-4, 7-6(5) in a tightly contested first-round match on grass, signaling his intent to regroup and chase a second title at the ATP 500 event, where he is the top seed.
Sinner’s loss to Alcaraz in the French Open final on June 8, 2025, was a bruising experience. Leading by two sets and holding three championship points in the fourth, Sinner fell 4-6, 6-7(4), 6-4, 7-6(3), 7-6(2) in a six-hour epic, described by The Athletic as one of the greatest Roland Garros finals ever. Despite the setback, Sinner showed resilience in Halle, adapting to the grass surface after the grueling clay season. “It’s never easy coming back after a loss like that, but I’m happy with how I played today,” Sinner said in his on-court interview. “Grass is a different challenge, and I’m just trying to find my rhythm.”
Against Griekspoor, ranked No. 27, Sinner displayed his trademark consistency, firing 12 aces and converting one of three break points in the first set. The second set went to a tiebreak, where Sinner’s composure under pressure shone, clinching the match after 1 hour and 38 minutes. His aggressive baseline play and improved serve, honed since his 2024 Australian and U.S. Open triumphs, were key. The victory sets up a second-round clash with either Fabian Marozsan or a qualifier, as Sinner aims to build momentum ahead of Wimbledon, where he is a favorite to complete the career Grand Slam.
The French Open final had tested Sinner’s mental fortitude. After dominating the first two sets, he faltered as Alcaraz mounted a comeback, saving three championship points and unleashing a barrage of drop shots and laser forehands. Sinner admitted post-match that the loss would linger: “I won’t sleep very well tonight,” he told The Independent. Yet, his ability to rebound from adversity is well-documented. In 2024, he faced a three-month anti-doping suspension, only to return and win the U.S. Open, silencing skeptics. His straight-sets semifinal win over Novak Djokovic at Roland Garros, 6-4, 7-5, 7-6(3), further underscored his growth.
