Kemper Open

The National, originally titled for sponsorship reasons as the AT&T National and later as the Quicken Loans National, was a professional golf tournament on the PGA Tour from 2007 to 2018. It was hosted by Tiger Woods and benefited the Tiger Woods Foundation. It was usually held either in late June or during the Fourth of July weekend in the Washington, D.C. area, except for 2010 and 2011 when it was held near Philadelphia. The National was a 72-hole stroke play tournament. It was one of a few events given "invitational" status by the PGA Tour and consequently had a field of only 120 players, as opposed to 156 players at most full-field tournaments. The first edition of The National in 2007 was held July 5–8 on the Blue Course at the Congressional Country Club in Bethesda, Maryland, northwest of Washington. The event returned to Congressional in 2008 and 2009 when it was held midway between the U.S. Open and The Open Championship to ensure a strong field of competitors. The National was part of the Open Qualifying Series that gave non-exempt players a chance to compete in The Open.
