Tiger Woods has hit his form at the perfect time as he aims to secure his fifth Masters win in a couple of weeks.
His win at the Arnold Palmer Invitational on Monday and a subsequent return to the number one spot in the World Rankings have been enough for bookmakers to expect him to finish atop the leaderboard in the opening major of the year.
Woods odds to win his 15th major are just plus-350 (7/2), giving him an 18 percent chance to be on top when the final round concludes on April 14 at Augusta National.
However, a strong field will assemble in Georgia, with the likes of Rory McIlroy and Phil Mickelson among the favorites to add to their trophy cases. There is also the usual multitude of top players who will be looking to make a name for themselves on golf's biggest stage.
