A slip down a flight of stairs has sent the top of the betting market for the 2017 Masters into flux.
Dustin Johnson is the world No. 1 and has been the favorite for weeks at the Westgate Las Vegas SuperBook, beginning Wednesday with 11/2 odds. Jordan Spieth and Rory McIlroy were the next highest, each at 15/2.
But after Johnson's agent announced that the reigning U.S. Open champ had slipped down some stairs in Augusta and injured his back, the lines were quickly adjusted and Johnson, Spieth and McIlroy now all sit as 7/1 co-favorites heading into the opening round.
The betting favorite hasn't won the Masters since Tiger Woods in 2005, and world No. 1 hasn't put on the green jacket since Woods in 2002.
Here's a look at the odds on each of the 94 participants teeing it up in the opening round:
7/1: Dustin Johnson, Jordan Spieth, Rory McIlroy
15/1: Jason Day, Rickie Fowler, Justin Rose, Hideki Matsuyama
20/1: Jon Rahm
25/1: Phil Mickelson
30/1: Adam Scott, Henrik Stenson, Justin Thomas, Sergio Garcia
40/1: Bubba Watson, Paul Casey, Louis Oosthuizen
250/1: Jhonattan Vegas, Byeong-Hun An, Andy Sullivan, Fred Couples
2000/1: Scott Gregory (a), Brad Dalke (a)
