Daniil Medvedev (1) d Pablo Carreno-Busta (4) 3-6 6-3 6-2
The Spaniard played very decent against the world no 2, but Medvedev kept his head in the game, and came out victorious! The Russian shrugged off the first set and had no pressure, as he broke in the first game of each of the last two sets to clean the Spaniard up.
Sam Querrey d Adrian Mannarino 6-4 6-3
The big serving American was just too good for the Frenchman. Mannarino has a good 1,2 punch from his serve, and his flat shots are good against taller opponents you need to reach down more, but it was not enough to break Querrey's streak. Querrey serving 18-3 aces with 97% win on first serve!
