A spot in the next round is at stake on Friday, when Anna Blinkova goes up against Bianca Andreescu in the Samsun quarterfinal. Bianca Andreescu comes in at 4 wins from the last ten. Anna Blinkova is 8-2 across recent matches.

On paper it's close: comparable ratings, comparable serve numbers, small margins everywhere. Blinkova comes in off a compressed schedule; Andreescu comes in off a compressed schedule. A tiebreak or two would surprise nobody, with Andreescu fractionally more likely to land the big points.
