- World number one Dustin Johnson says fatherhood has made him a better player as he prepares to defend his US Open title just days after the birth of his second son. The 32-year-old arrived at Erin Hills on Tuesday after a hectic 24 hours that saw him and wife Paulina Gretzky celebrate the arrival of baby River on Monday. Johnson, who has been installed as the favourite for this week's title in Wisconsin, described his unusual major championship build-up as an "awesome couple of days." "Everybody's healthy. Mom is healthy. The baby is healthy. So that's good," Johnson said. "It just gives you a whole new perspective on things," he said Wednesday. "Where before kind of golf was the most important and now my family is the most important. At the end of the day whether I'm having a good day or bad day, when I either see my family or talk to them, whatever, if I was upset or even if I was happy with the way I played, none of that matters."
