Olin Browne, of Tequesta, Fla., withdrew from the 2013 U.S. Senior Open Championship on Tuesday because of a back injury.
Browne, the 2011 U.S. Senior Open champion, was fully exempt and will be replaced by Jerry Vidovic, of Blue Island, Ill., the first alternate from the Hinsdale, Ill., sectional qualifying site.
The winner of the 1977 U.S. Amateur Public Links Championship, Vidovic shot 69 at Ruth Lake Country Club on June 24.
Two other players were also added to the field on Tuesday.
Jeff Whitfield was added when a spot became available when Kenny Perry, an exempt player, won last Sunday’s Senior Players Championship in Pittsburgh.
Whitfield, a professional from Weldon Spring, Mo., competed in sectional qualifying on June 24 at Quincy (Ill.) Country Club. Whitfield, who will play in his second U.S. Senior Open, shot 70 to share medalist honors, but lost in a playoff for the lone spot available to claim the first alternate position.
Kevin Coombs was added when an eligible senior player did not win last week’s AT&T National event on the PGA Tour.
Coombs, a professional from Camas, Wash., competed in sectional qualifying on June 24 in Camby, Ore., at Willamette Valley Country Club. Coombs, who will play in his first U.S. Senior Open and third USGA championship, shot 71 to earn the first alternate position.
