Harrington and Woods to lock horns again

Padraig Harrington and Tiger Woods are set to lock horns again today as the USPGA Championship gets underway in Minnesota.

The defending champion and the world number one have been paired together for the first two days of the event and will tee off today at around 2.35pm Irish time.

Last weekend, Woods beat Harrington into second place following an exciting finish to the Bridgestone Invitational in Ohio.

The event marked a return to form for the Dubliner, who has been struggling this season as he tries to develop a new swing.

Rory McIlroy, meanwhile, will be making his USPGA Championship debut today in a group that also includes US Open champion Jim Furyk and Germany's Martin Kaymer.

Graeme McDowell is paired with Americans Kenny Perry and Dustin Johnson, while Darren Clarke will tee off alongside Charles Howell III and Will MacKenzie.
