The Open 2015: Dustin Johnson birdies 18th for Open lead
USA's Dustin Johnson birdies the 18th hole after driving the green to give him a -10 total and a one-shot Open lead after two rounds at St Andrews.
The runner-up in last month's US Open completed his round 12 hours after the players were taken off the course earlier in the day due to high winds.
Britain's Danny Willett is a shot further back and will join Johnson in tomorrow's final group, with Scots Paul Lawrie and Marc Warren out just before them.
