Watch: Justin Thomas, Daniel Berger (not playing) chug beers on first tee

How confident was Team USA after grabbing a 9-3 lead midway through play on Saturday at the Ryder Cup?

Confident enough to start chugging beers on the first tee ahead of the afternoon fourballs.

Justin Thomas and Daniel Berger – both sitting the second Day 2 session, it should be noted – were tossed a couple of beers from the crowd and after revving up the partisanship, they slammed the brews.

Thomas then spiked his can.
