PORTRUSH, Northern Ireland (Reuters) - Shane Lowry knows from personal experience that a four-shot lead starting the final round of a major championship is hardly insurmountable, never mind the wicked weather expected to throw an extra layer of uncertainty into the British Open mix on Sunday.

Lowry led by four strokes after 54 holes at the 2016 U.S. Open at Oakmont, but struggled to a closing 76 as Dustin Johnson sauntered to victory.
