Other than Tiger Woods, the AT&T National failed to woo many of the top professionals.

No. 10 Hunter Mahan is the only other player in the field ranked in the world's top 10.

But thanks to sponsor's exemptions, the tournament will include two of the world's most recognizable amateurs. Beau Hossler, the 17-year-old California high school senior who made a splash by contending in last week's U.S. Open, will play at Congressional. Also in the field is University of Texas standout Jordan Spieth, who finished as the low amateur at the Open.

This will not be the first time Hossler has played Congressional. He qualified for the 2011 Open but failed to make the cut, shooting 76-77. This is the first time Hossler has received a sponsor's exemption to play a PGA Tour event.

Also receiving a sponsor's exemption is Patrick Cantlay, who turned pro Tuesday. The 20-year-old made the cut as an amateur last year at the Open at Congressional.
