Zizou Bergs is an energetic, front-foot Belgian whose grass results came late and then all at once: a first ATP title at Eastbourne and a first Wimbledon third round within a fortnight in 2026. He finished 14th in the GTC Grass Rankings with a GTC Grass Rating of 109, up from 94 and 30th before the season.

How Zizou plays on grass
Bergs plays quick, first-strike tennis that suits grass. He serves aggressively, looks for the forehand on the next ball and is willing to come forward early, which shortens points on a surface where the ball stays low. He brings a lot of visible energy to matches, and on grass that tempo can rush opponents who prefer longer rallies.
The risk is in the same package. He goes for a great deal on the second serve, and in his Wimbledon third-round match against Arthur Fery he hit 14 double faults, enough to swing a close five-setter. His return is more solid than spectacular, and against bigger servers he relies on a handful of points per set. An Arsenal score of 64 reflects a game with clear weapons and some loose edges.
His Nerve score of 60 is higher than his Arsenal mark for good reason. He won the Eastbourne final from a set down, came through a rematch with Ugo Humbert at Wimbledon and took Fery to a fifth-set tie-break. He competes well when matches turn long.
Grass record
Before 2026 his grass record was thin at tour level. He won the Ilkley Challenger in 2022, beating Jack Sock 7-6(7), 2-6, 7-6(6) in the final, and made his Grand Slam debut at Wimbledon that year as a wildcard, losing in the first round. He lost in qualifying in 2023 and in the first round in 2024, to Arthur Cazaux in five sets, and again in 2025.
His best grass week before 2026 came at ‘s-Hertogenbosch in 2025, where he beat Mark Lajal and Reilly Opelka to reach the final and lost to Gabriel Diallo 5-7, 6-7(8). That run showed his game could work on grass over a full week.
The 2026 grass season
The swing began badly. In Halle he lost in the first round to Taylor Fritz 6-7(4), 7-5, 4-6, and his rating sat at 94. He arrived at Eastbourne on a six-match losing streak at tour level and left with his first ATP title. In the final he beat Humbert 3-6, 6-1, 6-4; rain stopped play after three games on Saturday and the match finished on Sunday. He became the first Belgian man to win an ATP title on grass, rose to a career high and moved his rating to 98.
At Wimbledon he beat Humbert again in the first round and then the Portuguese qualifier Jaime Faria to reach the third round for the first time. There he lost to Fery in five sets after about 4 hours 40 minutes, the deciding set going to a tie-break. Even in defeat, the fortnight lifted his rating from 98 to 109.
Looking ahead to 2027
Bergs goes into 2027 defending a grass title for the first time, and Eastbourne points will matter for his ranking and his Wimbledon seeding. The useful targets are concrete: fewer double faults under pressure, and more return games won against big servers so that he is not living on tie-breaks. ‘s-Hertogenbosch, where he reached the final in 2025, is a natural place to start the swing. A first Wimbledon fourth round is a realistic aim, and a seeding would make that more likely by keeping him away from the leading players early.
