The 156 players scheduled to play in this week's 2019 U.S. Senior Open Championship began checking in to the locker room this weekend.
The temporary locker room was constructed "over top" of the putting green -- inside Notre Dame Golf's indoor practice facility on the west end of Warren Golf Course's practice area. Quite an engineering feat!
Every player has a locker -- if you're a past champion -- like Tom Watson -- your "full size" locker is located in a special row (along the back wall) of all of the former U.S. Senior Open Champions.
