Masters 2018 picks, best bets: Sergio Garcia among top long shots chasing Tiger Woods

Our advanced computer model says Sergio Garcia is one Masters long shot to back

Danny Willett stunned the golf world in 2016 when he won the Masters as an enormous 50-1 underdog. Could lightning strike twice and give us a second longshot champion on Sunday at Augusta? SportsLine's prediction model certainly thinks so.

The model, which was built by DFS pro Mike McClure, nailed the Masters and U.S. Open in 2017, calling career-defining wins for Sergio Garcia and Brooks Koepka. It was also all over Jordan Spieth at the 2017 British Open from the start, predicting the 24-year-old's third major victory.

Now that the field for the 2018 Masters is locked, SportsLine's prediction model has isolated four underdogs with odds of 18-1 or longer that could stun the golfing world and win this week's Masters, including one who's getting extreme odds. The entire field is chasing Spieth, Tiger Woods and the rest of the favorites, who are all going off at 12-1 or better.

One long shot you need to be all over at the Masters this year is Garcia; the 2017 Masters champion who is a 30-1 long shot and projected to make another serious run at the title, according to SportsLine.

The 38-year-old Spaniard ended an 0-for-73 stretch of futility in majors with last year's victory at Augusta National. Plus, Garcia has been red-hot this season, finishing T-7 or better in three consecutive starts on the PGA Tour.

Garcia ranks first on tour with a 68.7 scoring average and could join Woods (2001-02), Jack Nicklaus (1965-66) and Nick Faldo (1989-90) as the only players to win back-to-back Masters.

The model is also all over three additional underdogs who are real threats to take home the green jacket -- including a massive long shot with a strong track record at Augusta National. Anyone who bets on these long shots could hit it big.

So which long shots stun the golfing world this week at the Masters? Visit SportsLine now to see which massive long shots you need to be all over at the Masters to get a huge payday, plus get the entire projected leaderboard from the model that that nailed three majors heading into the weekend in 2017.
