"Sort of felt somewhat stress-free out there, if you can ever call golf at a U.S. Open stress-free."
This week marks the fifth time McIlroy has opened a major championship with three rounds in the 60s.
"Overall, yeah, pretty pleased with how today went, and feel like I'm in a good spot heading into tomorrow," said McIlroy.
While plenty confident in his ability, McIlroy admitted he was unsure what sort of boost he could take from his past major triumphs into Sunday's final round.
"I'm going out there to try to execute a game plan, and I feel like over the last three days I've executed that game plan really, really well, and I just need to do that for one more day."
