The Aussie will meet Pablo Cuevas or Emil Ruusuvuori for a spot in the last eight. Millman lost his only previous ATP Head2Head clash against Cuevas at the 2016 Miami Open presented by Itau and has not met Ruusuvuori.
Serbian wild cards compiled a 1-2 record on Monday at the Novak Tennis Center. Nikola Milojevic opened the tournament with an impressive 6-4, 6-0 victory against Federico Coria of Argentina, but Viktor Troicki was unable to join his countryman in the second round. Marco Cecchinato, the 2018 Roland Garros semi-finalist, needed 66 minutes to record a 6-1, 6-4 win against Troicki on Center Court.
