The Peque Schwartzman (15th in the ATP ranking) came from leaving the American Maxime Cressy and the British Daniel Evans on the road and had a remarkable performance, especially if one takes into account that in front of him he had one of the most winning rivals of the moment.
Ruud (10) was looking for his 50th victory this season, having achieved this year no less than 5 ATP Tour titles, in addition to helping Team Europe lift the Laver Cup, where Diego Schwartzman represented Team World.
The Norwegian also won both crosses this year between the two, at the Masters 1000 in Monte Carlo and Cincinnati.
For Diego Schwartzman, who arrives for first time to the quarterfinals in Indian Wells, the triumph opens up good prospects since his next rival It will be between Tommy Paul and Cameron Norrie.
The Peque came to 200 career victories, with 45 in Masters 1000 tournaments.
