Phil Mickelson of the US tees off at the 3rd hole on day two of the 112th US Open at San Francisco's Olympic Club on June 15, 2012 in California. Weather conditions were again ideal with sunshine and little wind, but such is the severity of the par-70, 7,170-yard hillside layout that only six players out of a starting field of 156 were under par when the second round commenced.
