Well, things just got a little more interesting at the U.S. Grand Prix. Mercedes' Lewis Hamilton during Friday's practices, but it's his teammate Nico Rosberg who will start on pole tomorrow afternoon.

Of course, Hamilton — winner of the inaugural race in 2012 — isn't far behind him. He'll start in second, followed by Valtteri Bottas in third.

"Great day, I'm very happy," Rosberg said at a post-qualifying press conference. "The balance was good. It was quite a challenge because the wind was changing." It's a breezy, cool and sunny day out at Circuit of the Americas, and while it's nowhere near as hot as last year's race, it has warmed up quite a bit throughout the day.

Hamilton experienced some issues with his brakes locking up during qualifying, the Mercedes cars have been having all season.

The official qualifying results are below . Should be a good race!
