Both players arrive here having lost the opening set and won anyway, which tells you most of what you need to know about how this one will go.
Sixth seed Anna Bondar dropped the first set 2-6 to Renata Zarazua before turning it around 6-3, 6-1. Alina Charaeva did something more impressive, coming back from 3-6 down to beat Sofia Kenin 7-6(4), 6-4. Kenin is a former Grand Slam champion and that is comfortably the biggest scalp of the Seoul first round.
Bondar is the more natural hard-court player of the two, though only just. Her game is built on consistency and depth rather than winners, and she is content to play twenty-shot rallies until an opponent breaks. Charaeva showed against Kenin that she can absorb pressure and lift her level in a tiebreak, which is a useful trait in exactly this kind of attritional matchup.
Expect long games, plenty of breaks in both directions, and a match that runs past two hours. Bondar's physical baseline gives her the edge in a third set.
Bondar in three.
