Cam Smith celebrates Open Championship by figuring out exactly how much beer fits in the Claret Jug

• Cam Smith won the Open Championship with a blistering final round at the Old Course at St. Andrews on Sunday.
• After lifting the Claret Jug, Smith said he planned to celebrate by filling the trophy with beer.

Cam Smith left the Old Course at St. Andrews on Sunday in the mood to celebrate.

After chasing down Rory McIlory with the help of a blistering back-nine performance, Smith had won the 150th Open Championship, taking the first major victory of his career.

The Aussie lifted the Claret Jug with a smile, and offered his plans for the night.

"I'm definitely going to find out how many beers fit in this thing," Smith said to the crowd. "That's for sure."

Smith reiterated his intentions in his post-victory press conference. Asked by reporters for his estimate, Smith said "I'm going to guess two, two cans of beer."

"I'll probably have about 20 Claret Jugs," Smith joked, earning a laugh from the room.

"I'm not sure, mate," Smith said. "To be honest, I'm really tired. It's been a long week, so I'd be surprised if I make it past 10:00 or 11:00 tonight."

Judging by the video, Smith did just fine.

While Smith pondered just how much beer he could fit in the Claret Jug, another former winner of the Open chimed in with a bit of helpful assistance.

Lowry, now an ambassador for Jameson, was making the most of the moment.

On Monday morning, Smith reported back with some news: His estimate of two beers had been largely correct.

Looking a bit haggard, but also honestly not all that much different from how he usually looks, Smith recounted his findings from the previous night.

"Hey guys, I guess everyone's been asking the question of how many beers fit in the Claret Jug," Smith said in a video posted to Instagram. "It's pretty much exactly two."
