A spot in the next round is at stake on Thursday, when Hubert Hurkacz goes up against James Duckworth in the Shanghai first round. Hubert Hurkacz has won 3 in a row and 8 of the last 10 overall. James Duckworth is searching for form, having lost 3 in a row (6 of the last 10).

The serve is where this match separates: Hurkacz has been winning 75.9% of first-serve points to Duckworth's 72.2%, and on hard that gap compounds fast. The edge belongs to Hurkacz — real, but not the kind you take for granted at this level.
