Luke Donald hits a volunteer during U.S. Open final round

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.
