Mariano Navone and Novak Djokovic meet in the first round at US Open on Sunday. Novak Djokovic has dropped 2 straight and sits at 7-3 over the last ten. Mariano Navone limps in on a 2-match losing skid, just 5 wins in 10.
The serve is where this match separates: Djokovic has been winning 70.7% of first-serve points to Navone's 62.4%, and on hard that gap compounds fast. Expect resistance, but the match-level math tilts clearly toward Djokovic.
