Scheffler enters Sunday's round with a massive four-shot lead at Royal Portrush in Northern Ireland, which has him on the cusp of claiming his fourth career major championship and his first ever Claret Jug. The top-ranked golfer in the world fired a bogey-free round on Saturday with ease, and nobody else seemed able to even make a dent in his lead.

So, this was weird: Rory McIlroy, playing his second shot from the rough on the 11th at Royal Portrush in Round 3 of the British Open, somehow managed to unearth another ball in mid-swing. The second ball was apparently embedded in the ground a few inches ahead of McIlroy's ball, and popped into the air as McIlroy's shot flew greenward.
