    Key factors

    • Olle Wallin has covered the +1.5 games handicap in five consecutive matches.
    • Zdenek Kolar has lost his last six matches and won only one of his last ten.
    • Over his last ten matches, Zdenek Kolar has a low percentage of sets and games won.
    • Olle Wallin is winning more games per match and is in better current form.

    Expected scenario

    Olle Wallin looks the stronger player here, backed by confident form and consistent game-winning. Zdenek Kolar, meanwhile, is struggling in all the key areas - both on return and on serve. The match may well be competitive, with both players offering resistance, but Wallin's form advantage should be enough for him to cover a positive games handicap.

    ⭐ Editor's Pick

    Given the difference in current form, Olle Wallin approaches this match with a noticeable advantage in games won and overall consistency of results. Zdenek Kolar is in the middle of a poor run, frequently losing without seriously contesting individual sets or games. Against that backdrop, the Swedish player's handicap looks justified: his form suggests he can count on at least an even games tally or even an edge by the final count, regardless of the match result. The pick is Olle Wallin - Games Handicap +1.5.
