17 year old Luis Augusto Quieroz Miguel, known as Guto Miguel, is quickly making his case as Brazilian tennis's next big name.

Despite his young age, the Goianésia born right-hander won his first ATP Challenger title alongside his older brother at the Costa do Sauípe Open in October 2025. Eight months on, with two more challenger tournament victories under his belt, Miguel climbed to ITF Junior World Number 1 after becoming the first Brazilian-born player to win the French Open Boys' singles title. Far from being satisfied, the young record breaker went on to secure the Wimbledon Juniors doubles title just weeks later, taking his tally to five trophies within the year. With the US Open Juniors fast approaching, Miguel will no doubt be hunting for his third Grand Slam Junior title in a row.
