Betfair spokesperson Sam Rosbottom said: “The first golf major championship of the year is back in its usual springtime slot after 2020’s delayed event was played in November and won by Dustin Johnson.
“The world number one is looking to retain the prestigious green jacket and leads the betting as the 9/1 favourite on Betfair Exchange.
“2020’s favourite Bryson DeChambeau failed to live up to expectations when finishing joint-34th, but he remains very popular amongst punters again and is 12/1 to add to his 2020 US Open win with a second major championship victory.
“Jordan Speith is 13/1 to win a second Masters jacket fresh from his recent win in the Texas Open. Jon Rahm and Justin Thomas are also 14/1.
