Patrick Reed, Keegan Bradley and Ian Poulter were some of the star names to launch their bid for a green jacket when the early action began at the Masters on Thursday.
After weeks of intense build-up the tournament was officially started when legends of the game Arnold Palmer, Gary Player and Jack Nicklaus - who have 13 Augusta titles between them - teed off for the honorary start in Georgia.
Charley Hoffman and Brian Harman of United States were the first players from the field to get started and the former enjoyed the better opening by going two under through seven - a bogey at the par-three fourth the only blot on his embryonic scorecard.
Arguably the biggest draw of the early starters was the group involving Reed, Bradley and Poulter, who teed off just after 9am local time.
Reed, a four-time winner on the PGA Tour, started in inauspicious fashion with a bogey at the first, while Poulter and Bradley both made par.
Gary Woodland, Kevin Streelman and former champions Vijay Singh and Jose Maria Olazabal were all one under par in the early stages.
The 2015 Masters has many subplots that will unfold over the course of the weekend, with particular focus on whether Rory McIlroy can complete the career grand slam at the first time of asking and how Tiger Woods will fare on his return from a self-imposed two-month hiatus.
Defending champion Bubba Watson will play alongside Gunn Yang Justin Rose in his opening round.
