Don't count Jason Day out of the U.S. Open just yet.
On a day where Oakmont is showing its teeth, par can be a player's best friend. But an eagle? That will allow you to make up a lot of ground in a hurry.
Just off the green in two on the 618-yard, par-5 12th hole, the reigning PGA Champion and current world No. 1 went ahead and did this for an incredibly timely 3:
The eagle brought Day to even par for the tournament -- 1 under on his round -- and within five shots of leader Dustin Johnson.
Five shots isn't as much as you might think at a course like Oakmont where anything can happen on the back nine. If Day can snag a couple more birdies on the way in and give the leaders something to think about, look out.
