A spot in the next round is at stake on Sunday, when Daniil Medvedev goes up against Hugo Gaston in the US Open first round. Daniil Medvedev limps in on a 2-match losing skid, just 5 wins in 10. Hugo Gaston is 6-4 across recent matches.
The serve is where this match separates: Medvedev has been winning 72.8% of first-serve points to Gaston's 65.8%, and on hard that gap compounds fast. The edge belongs to Medvedev — real, but not the kind you take for granted at this level.
