    Key factors

    • Sebov has won more than 5.5 games in 10 straight matches.
    • Matches involving Sebov average 21.6 games - which supports the bet on her individual total.
    • In her last 10 matches, Sebov has won 54% of all games played.
    • Marta Kostyuk didn't let Sebov take a set in their head-to-head, but the bet doesn't require winning a set.

    Expected scenario

    Kostyuk is the clear favourite here and should control the tempo from the start. That said, the trends and numbers suggest that even in a straight-sets loss, Sebov has a decent shot at reaching six games - through competitive sets or a run of holds.

    ⭐ Editor's Pick

    Marta Kostyuk's form makes her the clear favourite here - solid on serve, reliable in the big moments. But Kаtrine Sebov has shown a consistent ability to hold her game count even against top opponents, and the trend backs that up: she's cleared this line in all her recent matches regardless of the result. The pick is Katrine Sebov individual total over 5.5 games.
