Dustin Johnson makes U.S. Open trip after birth of second son

Dustin Johnson will come away a winner this week whether or not he successfully defends his U.S. Open title.

Johnson's fiancee, Paulina Gretzky, gave birth Monday to their second son. Johnson left afterward for Erin Hills, the Wisconsin site of golf's national championship.

He traveled to Erin Hills on Tuesday, after Gretzky gave birth by Caesarean section in the Los Angeles area.

Johnson spent some time at the 7,741-yard course after missing the cut at the Memorial last week in Dublin, Ohio.

Johnson and Gretzky also have a 2-year-old son, Tatum. They announced in February that Paulina, daughter of hockey great Wayne Gretzky, was pregnant with another boy.

During the opening of his winery and distillery Wednesday night in Niagara-on-the-Lake, Ontario, Wayne Gretzky told The Brantford Expositor that his daughter's pending delivery was "taking up all of our time right now. Another little boy will be born between now and next Monday."

USGA officials have scheduled Johnson for a 4 p.m. CT news conference Wednesday, a day later than prominent players normally hold their media sessions at major championships. Johnson requested that time slot, according to an official. He claimed his first major victory at Oakmont last year and is looking to become the first man to win back-to-back U.S. Opens since Curtis Strange did it in 1988 and '89.

He won three consecutive tour starts earlier this year before pulling out of The Masters after he said he hurt his back and elbow in a staircase fall.
