James Hahn missed the cut in his Masters debut by a shot. He could have saved himself the shot he needed to play the weekend, and no one probably would have noticed.

That's because Hahn called a penalty on himself on the first green on Friday when his ball moved.

Hahn made a bogey on No. 1 en route to a 2-over 74 that put him at 3 over through two rounds and a shot off the cut line.

Missed cut by 1.Sometimes you don't get rewarded for doing the right thing,but it doesn't mean you shouldn't do the right thing. #integrity — James Hahn (@JamesHahnPGA) April 11, 2015

The 33-year-old new dad may not have made the cut at Augusta National, but earned a ton of respect for showing his integrity.
