Tallon Griekspoor and Ze Zhang meet in the round of 16 at Hertogenbosch on Thursday. Tallon Griekspoor comes in at 3 wins from the last ten. Ze Zhang comes in at 4 wins from the last ten.

The two have never played — a first meeting always adds a layer of uncertainty the numbers can't fully capture.

The serve is where this match separates: Griekspoor has been winning 73.3% of first-serve points to Zhang's 65.8%, and on grass that gap compounds fast. Zhang comes in off a compressed schedule. The edge belongs to Griekspoor — real, but not the kind you take for granted at this level.
