Player of the week
Derek Ernst. How improbable was Ernst’s win at the Wells Fargo Championship at Quail Hollow? He was driving toward Athens, Ga., to play in a Web.com Tour event when he got a phone call saying that, as the fourth alternate, he had a spot in the Wells Fargo field. Then he went out and won, overcoming Phil Mickelson, Lee Westwood, and Rory McIlroy, then beating David Lynn in a playoff. Ernst, a 22-year-old rookie from UNLV, arrived in Charlotte, N.C., ranked 1,207th in the world. After his victory, he’s up to No. 123.
