Phil Mickelson has withdrawn from the 2017 U.S. Open Championship on Thursday, June 15 because of a previously scheduled family commitment.
Mickelson, who was fully exempt and has competed in 26 U.S. Opens, will be replaced in the field by Roberto Diaz, of Mexico, the first alternate from the Summit, N.J. sectional qualifying site.
Diaz, a 30-year-old, shot 65-70--135 at Canoe Brook County Club’s North and South Courses on June 5. He is playing in his first U.S. Open.
Mickelson, who had played in 23 consecutive U.S. Opens which dates to 1994, is a six-time U.S. Open runner-up (1999, 2002, 2004, 2006, 2009, 2013).
