Luke Donald started his final round of the U.S. Open with consecutive pars and seemed to be in pretty good shape, until things started to go a little wayward -- literally -- on the par-3 third hole.
Donald's tee shot on the long par-3 sailed left and struck a volunteer following the group ahead. The volunteer, a young lady, remained on the ground for a number of minutes and was visibly shaken when she stood up. Donald apologized and gave the volunteer a signed glove, who reportedly told him not to worry.
Donald bogeyed the hole, and went on to play the next three holes in four-over par.
