Tiger Woods has been partnered with Ernie Els and Justin Rose for the first two rounds of this week's Arnold Palmer Invitational in Florida.
Woods, who has won at the Bay Hill course on seven previous occasions, can regain the world number one spot from Rory McIlroy with victory.
A win would also see Bay Hill move level with Torrey Pines as Woods's most successful course.
McIlroy is not competing at the PGA Tour event this weekend.
