World number one Jason Day feels he is in a position to add the U.S. Open to growing list of trophies after impressing in Pennsylvania on Saturday.
Day banished the memories of his woeful opening on Thursday with a four-under-par 66 at Oakmont Country Club.
While most of the field did not complete their rounds, Day - who had a first-round 76 - posted four birdies and an eagle to surge to one over, just six shots behind leader Shane Lowry.
Lowry is five under through 14 holes.
Afterwards, Day told reporters: "I mean even par was the final score for me that I was trying to reach.
"I think Shane's playing some pretty good golf now. But I can't be aggressive out there and start firing at pin itself and making silly mental errors.
"If I can get to even par, great. If I can get to one under, great. I've got to just kind of check the boxes and try and take them as they come. Hopefully, at the end of the day, I'm under par somewhere and that definitely gives me a shot."
All of the players in front of Day are bidding to win their first major title.
Lowry, Andrew Landry, former world number one Lee Westwood, Sergio Garcia, Dustin Johnson, Branden Grace and Scott Piercy have not won majors.
Whether that is an advantage for experienced Day - last year's US PGA Championship victor - remains to be seen.
"Depends how they look at it. If they want to go out there and they think they're ready to win a Major, then it's obviously going to be tougher because they're going to be focused and ready," he said.
"I don't think it matters in times like this when it's just mentally and physically gruelling. Not only when you're out there, when you get back, you're always thinking about it at night time.
"It's good to have a Major under my belt, but I'm just trying to win the tournament. That's all I want to do is try to win the tournament. I think I've given myself an opportunity getting there. We'll see how those guys go in the morning and hopefully, I'll be there."
