We take a look at five European Senior Tour members and their groups for the first two rounds of this year's Masters Tournament.
Bernhard Langer
Two-time Senior Open Championship Presented by Rolex winner Bernhard Langer has been drawn with European Tour members Alex Noren and Patrick Reed.
Noren hit the headlines in 2016 after winning four times on the European Tour, moving to as high as ninth in the Official Golf World Rankings, while Reed will be forever remembered for his epic Sunday singles dual with Rory McIlroy at The 2016 Ryder Cup.
Langer, the dominant golfer on the over-50s circuit, heads into this weekend on the back of a record-breaking run in the United States. For the last 35 rounds, Langer has shot under par - a formidable feat for any golfer at any level.
Winner of the Masters in 1985 and 1993, Langer has made the cut three out of the last four years, finishing eighth in 2014. He started the final round in 2016 just two shots off the lead.
Ian Woosnam
Ian Woosnam, winner of the Masters Tournament in 1991 will tee it up with Americans Brad Dalke and James Hahn for the first two rounds of this year's edition - the Welshman's 30th visit to Augusta.
Hahn is a two time winner on the PGA TOUR, and has played at Augusta National just once, in 2015. He has, however, made the weekend at the last three Major Championships.
Dalke received an invitation to the Masters after finishing runner-up to Curtis Luck at the 2016 U.S. Amateur Championship.
José María Olazábal
José María Olazábal, Ryder Cup Captain in 2012, has been drawn with two US Ryder Cup players for the first two rounds of this year's Masters Tournament.
The Spaniard, winner of the Green Jacket in 1994 and 1999, will be joined by Ryan Moore and Webb Simpson. Moore played in The 2012 and 2014 Ryder Cups and Simpson made his Ryder Cup debut at Hazeltine National last year.
As well as his U.S. Open victory in 2012, Simpson has three PGA TOUR wins to his name, and Moore is a five-time winner in the United States.
Sandy Lyle
In 1988, Sandy Lyle became the first golfer from Great Britain to win the Masters Tournament after triumphing by one stroke from Mark Calcavecchia.
The Scot will be joined by English amateur Scott Gregory and America's Sean O'Hair. O'Hair is a four-time winner on the PGA TOUR and Gregory secured his spot at Augusta after winning last year's Amateur Championship at Royal Porthcawl Golf Club, host venue of the 2017 Senior Open Championship Presented by Rolex.
Lyle will be the player with the most Masters appearances at this year's tournament. He has played every year since 1985 and this year will be his 36th start.
Vijay Singh
The big Fijian returns to the site of his 2000 victory for the 24th consecutive time. Singh, a former World Number One and three-time Major Champion will be joined by two South American golfers for Thursday and Friday's rounds.
Toto Gana, the 19 year old Chilean, succeeded at the Latin American Amateur Championship earlier this year, winning a three-man play-off, booking his place at Augusta.
Argentina's Emiliano Grillo makes up the three-ball. Grillo is currently 33rd in the world and won on the PGA TOUR in 2015.
