Jordan Speith is in prime position to win the Masters, maintaining the lead during the final round at Augusta. The 21-year-old has begun the last day of the hallowed tournament after setting a scoring record for 54 holes of 16 under par. He is playing alongside British contender Justin Rose in the final, showcase pairing, and will be looking to avoid the disappointment of last year, when he finished runner-up. Some of his American rivals, such as Tiger Woods, have slipped down the leaderboard. But others, including Dustin Johnson and Phil Mickelson are still posing a threat. Jordan Speith, pictured during his final round on Sunday, is in prime position to win The Masters, taking a four shot lead into the final round at Augusta . He is playing with British contender Justin Rose, who began the day four shots off the pace . Spieth, who squandered a front-nine Masters lead on Sunday last year and settled for sharing second behind Bubba Watson, is the man to beat for the top prize of $1.8 million at the $10 million event. 'Last year definitely left a bad taste in my mouth,' Spieth said. 'Looking at trying to get some revenge. I've got a long way to go still.' The spotlight belonged to Spieth, who could break Tiger Woods' 1997 tournament record of 18-under 270 by shooting 69 in the final round. The former world number one Woods started the day some shots back, and caused concern on the 7th hole when he seemed to injure his finger. He then pulled up on the 8th tee, shaking off the same hand while his girlfriend Lindsey Vonn watched from the crowds. If he wins, Spieth would become the second-youngest winner in Masters history, five months older than Woods when he won his first major in 1997. Spieth could also become only the fifth wire-to-wire winner in Masters history, joining Craig Wood in 1941, Arnold Palmer in 1960, Jack Nicklaus in 1972 and Ray Floyud in 1976. Spieth is the first player since Greg Norman in 1996 to own the outright Masters lead after each of the first three rounds, but Norman squandered a six-stroke lead in making the greatest last-day collapse in major golf history and lost by five to Nick Faldo. Tiger Woods  waits to play a shot on the first hole during the final round. He started the day further down the field looking to make up lost ground . The former world number one let go of his club and shook his hand after hurting his wrist during after playing a shot in pine needles . His girlfriend, gold medal skier Lindsey Vonn, was spotted walking up the first way as he got his round underway . She has been on hand to support her beau at Augusta throughout the week . No player in Masters history has ever reached 19-under at any stage of the tournament but Spieth flirted with it Saturday, making four birdies in five holes to stand 18-under before a double bogey at 17 and a 10-foot par save at 18, and could threaten again Sunday. With 22 birdies through 54 holes, Spieth broke Woods' record of 21 in 2005 and is on pace to shatter Mickelson's Masters 72-hole birdie total record of 25 from 2001. But Spieth has not made the Masters a runaway. Rose, who closed with five birdies in the last six holes Saturday, is trying for a second major crown - 22 months after his breakthrough at Merion. And Mickelson is still in position to potentially become the second-oldest winner in Masters history after Jack Nicklaus, who was 46 when he won in 1986. Mickelson has only one top-10 in his past 31 starts but it was a runner-up effort at last year's PGA Championship. Mickelson won the 2004, 2006 and 2010 Masters, as well as the 2005 PGA Championship and 2013 British Open. Should he win Sunday, he would match Faldo and Lee Trevino as six-time major champions. Spieth (above with girlfriend Annie Verret on her 21st birthday) is the first player since Greg Norman in 1996 to own the outright Masters lead after each of the first three rounds . On Saturday it was reported that the Dallas, Texas native has just bought $2.3million on a stunning Texas mansion and has a gorgeous girlfriend, Annie Verret, who also happens to be his high school sweetheart. Spieth grew up the oldest of three siblings to Shawn and Chris Spieth. Steven, Spieth's younger brother, is an athlete as well, and plays basketball for Brown University. Then there is his youngest sibling Ellie, who was born with a neurological disorder that places her on the autism spectrum, and who has played the biggest role in shaping her brother's career according to Spieth's mother. She says Ellie helps the young superstar stay so grounded. 'Jordan wouldn't be where he's at today if he didn't grow up with Ellie,' said Mrs. Spieth in an interview with ESPN. 'Jordan realizes this isn't real life at the Masters. Trying to sit around and have dinner when his sister doesn't want to eat when everybody else is eating and has a fit, that's real life.' Spieth on his own website has said: 'Being Ellie's brother humbles me every day of my life.'
