Tiger Woods hits balls at the practice range as he prepares for the Masters golf tournament at the Augusta National Golf Club in Augusta, Ga. on Sunday, April 3, 2011.

*Tiger Woods will be playing the first two days of the Masters with U.S. Open champion Graeme McDowell, who rallied from a four-shot deficit to beat Woods last December.

Also in their group for the opening two rounds will be Robert Allenby, the Associated Press reports.

Defending champion Phil Mickelson is in the same group with U.S. Amateur champion Peter Uihlein, one of the many traditions at Augusta National. Also in their group is former U.S. Open champion Geoff Ogilvy.

Augusta National opened its gates after a 45-minute delay this morning to give workers time to clean debris from overnight storms before practice rounds.

The storms toppled trees and some power lines across town. There was no word on any damage to the golf course.

Chain saws could be heard from various corners of the course Tuesday. In the final minutes before fans were allowed on Augusta National, numerous carts were hauling away tree limbs. Some marshals were picking up debris from fairways.
