The 23-year-old Italian's next opponent in Australia will be either No. 13 Holger Rune or Miomir Kecmanovic.
After eliminating Giron, who was trying to get to the fourth round of a major for the first time, Sinner was critical of himself, pointing specifically to his 16-of-24 success rate on points when he moved forward.
“The percentage of my net game was not really good,” Sinner said with a chuckle.
“For sure, if I want to go on in this tournament, I have to improve,” he added. “So hopefully in the next round, I'm able to raise my level.”
