World No 1 Dustin Johnson has no distractions ahead of Open

World number one Dustin Johnson will have no distractions at Royal Birkdale this week as he seeks to avoid a third successive missed cut.

The American failed to make the weekend at the Memorial Tournament and also for his US Open title defence at Erin Hills last month.

In between those two events his fiancée Paulina Gretzky gave birth to their second child River, a brother for two-year-old Tatum.
