Arron Oberholser won his first PGA tournament on Sunday at the storied AT&T Pebble Beach National Pro-Am. Playing the famous course that he grew up near, Oberholser had a comfortable lead going into the back nine in the final round. It appeared to be smooth sailing. Then his nerves got ahold of him and he started to melt down on the back nine. It took a combination of sheer concentration, an uncharacteristically bad final-round performance by Mike Weir, who was co-leader heading into the day, and a lucky break on the 15th hole to earn him his first PGA victory.

Oberholser had a six-shot lead with six holes to play - basically a slam dunk in pro golf. But that didn’t calm his nerves, and it began showing on the 13th and 14th holes, where his shots started flying all over the place. He went left and right, taking bogey on both holes and breathing hope in eventual second-place finisher Rory Sabbatini.

Then his tee shot on 15 sailed wildly to the right and hit the cart path - twice. It could have spelled disaster, but he caught a lucky break, hitting a tree and finding his ball with a clear shot to the green. He then redeemed himself, hitting a wonderful clutch shot to within 8 feet of the hole. He turned what might have been double-bogey into birdie and sealed the championship. Obeholser’s comments after the win say it all:

I get up there [to his second shot at 15] and I was like: Wow! I mean, that was a good break. And those are the breaks you need sometimes to give you the confidence to push you through.

Oberholser ended up shooting even-par 72 for the day and won by five strokes, matching the largest victory margin in Pebble’s 77-year Pro-Am history.
