Following the second round, Lee Westwood and Ian Poulter, head the Masters leaderboard but Tiger Woods is the new favourite at 13/5.
The two Englishmen are in a handy position at eight under to win their first major. Ladbrokes make Westwood 4/1 with Poulter 9/2 at Stan James. World number one Woods is ominously close however just two shots behind and Sportingbet make him their 13/5 favourite in Augusta.
US PGA winner Yong-Eun Yang is a shot further back and he is 33/1 at Boylesports to claim another major title.
