Bryson DeChambeau kept entertaining long after he won the U.S. Open.

HOUSTON – Winner of the 2010 U.S. Open, McDowell joins countryman Darren Clarke, the 2011 British Open champion, in the field that also features No. He also played in 2006 when the Shell Houston Open made its debut on the Tournament Course. McDowell, or "G-Mac" as he is known on the European Tour, has actually played in another Shell Houston Open. Defending SHO champion Phil Mickelson won his 40th PGA TOUR event last weekend at the AT&T Pebble Beach National Pro-Am. "We feel very good that both Lee Westwood and Graeme McDowell, who are now PGA Tour members, committed to our event early."
