The 27-year-old, Raonic beats American Sam Querrey 7-5, 2-6, 6-3 --to pick up his fourth match win of the season and is seeking to capture his ninth career ATP Tour title. He’ll be up against the eighth-ranked player in the world in Argentina’s Del Potro, who beat German Philipp Kohlschreiber 3-6 6-3 6-4 in the day’s other quarter-final. “I am very happy I was able to put it together today,” Raonic said. “I’m in the semis. I am happy with that. I know I can play better.”

Former US Open champ Del Potro stepped up his effort for a second straight tournament victory with his over two hour quarter-final win. Del Potro, who won a title earlier this month in Acapulco, Mexico, deal off a strict challenge from Kohlschreiber. The 29-year-old Del Potro improved to 15-3 on the season as he is looking to get back into the Indian Wells final for the first time since 2013, when he lost to Rafael Nadal.

Raonic lost in the final of this event in 2016 and has now made it to the semi-finals in his last three appearances. Raonic didn’t play in Indian Wells last year because of a string of injuries and surgeries that decimated his season. “It’s been a catastrophe,” he said of the time off due to injuries. The list of things that have put him in the infirmary in the past year is lengthy and might have sent another person into permanent retirement.
