Zhizhen Zhang and Rei Sakamoto meet in the first round of US Open qualifying on outdoor hard courts, with both players ranked in the low 160s. Zhang, the 29-year-old Chinese veteran with a career-high ATP ranking of 31, brings greater main-tour experience and leads the head-to-head 1-0 after a straight-sets win over Sakamoto in a February 2026 Brisbane Challenger semifinal on hard. The younger Japanese player, however, holds a stronger 2026 win rate near 60 percent, multiple recent Challenger titles, and solid hard-court results that have pushed his ranking to a career high of 148. Recent form shows Zhang coming off mixed challenger outcomes while Sakamoto has posted consistent results on the surface. The matchup pits Zhang’s physical size and serve against Sakamoto’s rising momentum and aggressive baseline game in a tightly contested encounter.
