A spot in the next round is at stake on Wednesday, when Otto Virtanen goes up against T. Pereira in the Porto round of 32. Otto Virtanen has won 5 of the last 10. T. Pereira has dropped 2 straight and sits at 4-6 over the last ten.

Hold strength tells the story — 74% versus 65.8% on first-serve points in Virtanen's favor. The edge belongs to Virtanen — real, but not the kind you take for granted at this level.
