INCHEON, South Korea — Dustin Johnson hasn't lost a match while playing for the United States in nearly four years.
Part of that is because he's very good.
Any discussion about American talent in golf would have to include the 31-year-old Johnson, who has won in every PGA Tour season since he was a rookie in 2008 fresh out of Coastal Carolina. He has chased majors, falling short either by bad luck (Chambers Bay), a bad shot (Royal St. George's), bad golf (Pebble Beach) or a bad setup (bunkers at Whistling Straits).
But there's another reason that Johnson hasn't lost a match in so long.
