If you planned to make a longshot wager on Jon Rahm to win this year's Masters, your window may have closed.
Rahm broke out from a crowded leaderboard Sunday to earn his first PGA Tour win at the Farmers Insurance Open. The victory means the former top-ranked amateur will officially be among the players teeing it up at Augusta National in April.
The Westgate Las Vegas SuperBook already had Rahm listed at 60/1 - modest odds considering he wasn't yet in the field. But after his victory at Torrey Pines, the outlet trimmed his odds to 40/1, leaving the Spaniard behind only 14 other players.
Jordan Spieth remains the betting favorite at 8/1, though the odds on his two closest competitors both dropped over the last week. Jason Day fell from 9/1 to 10/1 after a missed cut in San Diego, as did the odds for Rory McIlroy after the Ulsterman disclosed he expects to be out until March because of a rib injury.
Betting odds on Tiger Woods fell from 20/1 to 25/1 after Woods missed the cut in his first competitive start of the year.
Here's a look at the betting odds for several top names, with the season's first major only nine weeks away:
8/1: Jordan Spieth
10/1: Jason Day, Rory McIlroy
12/1: Dustin Johnson
15/1: Hideki Matsuyama, Justin Rose
