It's been all fun and games (and the occasional drops of rain) so far this week in Ireland at the 2011 Solheim Cup.

Of course, that all changes Friday when the first foursomes match tees off at 2:40 a.m. EST at Killeen Castle.

(Pressure, anyone?)

In the meantime, be sure to check out all of Team Titleist's behind-the-scenes pictures from the Solheim Cup practice rounds, including a peek inside the lockers of our Titleist golf ball players.
