Cameron Smith’s first reaction to winning the Open Championship on Sunday was seeing how he was going to turn the Claret Jug into the Claret Chug.

Smith came all the way back to win the tournament. He started the fourth round four strokes behind Rory McIlroy and Viktor Hovland and his dominance on the green helped him catch the leaders and eventually catapulted him into first place.
