Zhizhen Zhang, slipping to No. 242 on protected ranking after a career-high No. 31 in 2024, shows concerning form with a 4-6 YTD record and a recent Munich defeat to Darderi, marking limited tour-level clay success—his first win on the surface since 2024 Houston came only in March. No head-to-head exists; traders eye Kopriva's surface edge, rest from Munich, and potential weather delays, though upsets remain common in early Masters 1000 rounds.",
