Seamus Power and Rory McIlroy will also be in action later this afternoon
Tiger Woods returns to action in the Genesis Invitational on the PGA Tour in California today.
It's a tournament Woods has never won - he tees off at 5:25pm Irish time.
Just after 4:30pm, Seamus Power begins his challenge, and Rory Mcllroy - who will become the new world number one if he wins this week - is out just before 8 o'clock Irish time.
Woods only played three tournaments last year as he underwent ankle surgery.
Leona Maguire is level par after two holes of her opening round at the Saudi Ladies International, currently six shots off the lead.
