    Zhizhen Zhang Player Overview

    Zhizhen Zhang arrives in poor recent form, with just three wins from his last ten matches. In the first round he beat Marin Cilic comfortably. Over his last ten matches he has lost three in straight sets, which points to difficulties when things go against him. He wins 48% of games on average, and holds serve in 71% of cases - a steady figure, though below his opponent's current metrics. His return games are below average, which makes things harder against stronger opponents.

    Key factors

    • In 6 of Rei Sakamoto's last 7 matches, the total games were under 23.5.
    • The average number of games per match for both players does not exceed 24.
    • Zhizhen Zhang has lost three matches in straight sets in the last ten, which reduces the likelihood of an extended contest.
    • Rei Sakamoto wins 65% of sets, which favours two-set outcomes.
    • Their head-to-head meeting ended 2-0 in sets.

    Expected scenario

    The most likely scenario is a quick, one-sided match - Rei Sakamoto regularly finishes matches in two sets, while Zhizhen Zhang suffers straight-set defeats fairly often. The probability of a third set is low, so a bet on the under looks a reasonable choice for this match.

    ⭐ Editor's Pick

    Rei Sakamoto is in considerably better form: seven wins from ten matches and a high set-winning percentage suggest he can control the match from the opening rallies. Zhizhen Zhang has struggled against stronger opponents and has frequently lost without winning a set, which further reduces the chances of a third set or extended games. Both players tend to get through their matches relatively quickly - the average total rarely exceeds the stated line even when a match starts evenly. The pick is Total Games - Under 23.5.
