Kim ahead by 4 in Wyndham

Si Woo Kim followed his tournament-record 10-under-par 60 with a third-round 64 to increase his lead to four strokes in the Wyndham Championship at Greensboro, N.C.

The 21-year-old South Korean player had an 18-under 192 total at Sedgefield — a stroke off the tournament 54-hole record set by Carl Pettersson in his 2008 victory.

Rafa Cabrera Bello was second after a 65 in the PGA Tour’s regularseason finale.
