Cruz Lleyton Hewitt (born 11 December 2008 in Sydney) is an emerging Australian tennis player who has already reached a career-high ATP singles ranking of No. 370 (achieved on 3 August 2026) and a doubles ranking of No. 690. He is the son of legendary former world No. 1 and two-time Grand Slam champion Lleyton Hewitt, and actress/singer Bec Hewitt, growing up in the Bahamas before relocating to Melbourne and later the Gold Coast to train at the KDV Tennis Academy. After claiming his first ITF junior title at age 13 in Fiji in 2022, he made his junior Grand Slam debut at the 2024 Australian Open and surged to an ITF junior ranking of No. 38 by early 2026. He notably reached the 2026 Wimbledon boys' singles final without dropping a set, before losing to Jordan Lee in three sets. Turning professional at 14 in September 2023, Cruz is now building a promising career, though he will always carry the weight of a remarkable sporting lineage that includes his AFL-playing grandfather and great-uncle.
