As the 148th Open Championship makes its arrival at Royal Portrush in Northern Ireland, all eyes are officially on four-time major championship winner Rory McIlroy. Playing in his home country and seeking a second Open Championship, McIlroy was recently bumped up to the top of the odds board to win the tournament at 8-1.

Previously, that spot held by Brooks Koepka, who like McIlroy is seeking a fifth major championship, but unlike McIlroy has yet to hoist the Claret Jug. Koepka remains high on the odds board, just a notch below McIlroy at 10-1 alongside fellow American Dustin Johnson. They are followed by Jon Rahm at 16-1 and three-time Open Championship winner Tiger Woods at 18-1. Of course, Woods already took one major this year in winning the 2019 Masters back in April.

While some players like Henrik Stenson (30-1) and Matt Kuchar (30-1) have seen their odds improve in recent weeks, Jordan Spieth has been among the golfers moving in the opposite direction on the board. As we enter the week of the championship, Spieth is barely hanging on as one of the top two dozen names on the board at 40-1. 

From Rory's post as the betting favorite to Phil Mickelson's long shot odds at 100-1, here's how the top of the odds board looks heading into the 2019 Open Championship, according to the Las Vegas Superbook. Be sure to check out our expert picks and predictions for the 2019 Open.
