2017 Masters Odds Roundup: Johnson, McIlroy, Spieth Betting Lines, Analysis

Two of the top three golfers on the betting board at sportsbooks monitored by OddsShark have never won the Masters, making the 2017 tournament starting Thursday at Augusta National intriguing despite the absence of four-time champion Tiger Woods for the second year in a row and third time in four years.

Woods won his first green jacket 20 years ago but is not ready to return from a back injury.

Instead, fellow American Dustin Johnson headlines the field as the +550 favorite (bet $100 to win $550) on the 2017 Masters odds off wins at the Genesis Open, WGC-Mexico Championship and WGC-Match Play, which are the last three PGA tournaments that he entered.

Johnson also placed third at the Pebble Beach Pro-Am in February, and he will be trying to earn his first career victory at the Masters after tying for fourth at Augusta last year.

Another American, Texas native Jordan Spieth, will be looking for his second green jacket and hopes to bounce back from an epic collapse there in 2016 following his first win in 2015. Spieth, who is listed at +800, blew a five-shot lead on the back nine last year to allow England's Danny Willett to steal a second straight title from him.

Willett is a +12500 longshot to repeat, and he has struggled on the tour since then. The Masters was his only PGA victory in 2016, and this year his best finish was fifth at the Maybank Championship, which is co-sanctioned by the Asian Tour and European Tour.

Northern Ireland's Rory McIlroy is +700, and like Johnson, he too is seeking his first green jacket. Also like Johnson, McIlroy's best career finish at the Masters was fourth in 2015, when Spieth tied the tournament record set by Woods in 1997. McIlroy has played well on the PGA Tour so far this year, with three top-10 finishes in four events.

Other top golfers to watch include Hideki Matsuyama, Rickie Fowler and Jason Day, who are each listed at +1800. Day tied for second at the Masters in 2011, Fowler tied for fifth in 2014 and Matsuyama placed fifth in 2015 for their best finishes at Augusta.
