Sinner reached the Paris semi-finals for the first time after beating Shelton 6-3 6-3 - his seventh straight win over the American.
"I'm very happy," the 24-year-old told Sky Sports. "It was a very, very tough match.
"At times you don't have a lot of control because of his incredible serving, but today I felt like I was returning very well.
