Shane Lowry steeling himself for most challenging day of his career at Open

A day of golfing perfection from Shane Lowry took the Irishman to the verge of Open Championship victory at Royal Portrush but the 32-year-old is steeling himself for the most challenging day of his career tomorrow.

Lowry’s bogey-free, eight-under-par 63 today, the best since Royal Portrush was updated with two new holes ahead of The Open’s return for the first time since 1951, has given him a four-shot lead over England’s Tommy Fleetwood going into the final round.
