Three-time major winner Brooks Koepka and fellow American Bryson DeChambeau share the lead after an enthralling opening round of the 83rd Masters.

Koepka shot a bogey-free 66 while DeChambeau, who hit the pin with his second shot to the last, tapped in for birdie to also score six under.

Three-time champion Phil Mickelson, bidding to become the oldest major winner in history at the age of 48, is third on five under, while 43-year-old Englishman Ian Poulter is joint fourth alongside world number two Dustin Johnson on four under.

Spain's Jon Rahm and 2013 Masters winner Adam Scott are in a group on three under while four-time champion Tiger Woods is a shot further back on a congested leaderboard.

Northern Ireland's Rory McIlroy began his quest for the only major he is yet to win with a one-over 73, while world number one Justin Rose, who was four over after nine, holed birdies on the 15th and 17th holes as he carded a 75.
