In 2025, Tristan Schoolkate broke into the Top 100 in August and reached a career-high No. 95 in September after advancing to the US Open second round, and he made his first ATP quarterfinal in Los Cabos. He earned tour-level wins over Taro Daniel at the 2024 US Open and again at the 2025 Australian Open (as a wild card), then took a set from eventual champion Jannik Sinner in the second round. At Challenger level, he won titles in Brisbane and Ilkley in 2025 after claiming his first Challenger title in Guangzhou in 2024. In his Indian Wells debut last year he fell in the first round of qualifying.
