UPDATED: August 22, 2013, 9 p.m. - Miller had quite the professional debut this past week at Old Westbury Golf and Country Club. The 21-year-old finished alone in third on the heels of a brilliant final round 4-under 67, that included four birdies on his final nine holes. 

Following a three-putt bogey on the uphill par 3 14th, Miller rebounded with a remarkable 3-iron from 255 yards away on the par 5 16th to set up an easy two-putt birdie. He missed two more birdies by inches on the 17th and 18th but was still able to match the championship low score.

Miller, 21, who recently advanced to match play at the U.S. Amateur at The Country Club in Brookline, Mass. (and one of only three players out of 312 to shoot two under par rounds during stroke play qualifying), will now be vying for a share of the $125,000 Met Open purse ($27,500 awarded to the winner).

"After the U.S. Am when I didn't make it through, and I made the decision, I kind of mentally prepared for the Met Open to be my first professional event," he said. "The Met section has been unbelievable to me, I'm really just grateful for this to be my first pro start."
