After overtaking Brooks Koepka and vaulting to a +800 favourite on the 2019 British Open odds, Rory McIlroy has also emerged as the clear favourite to be the tournament leader after the first round, sporting +1800 odds on those British Open betting props at sportsbooks monitored by OddsShark.com.
McIlroy has tallied top-five finishes in each of his past four appearances at this event, and will be aiming for his first major tournament victory in five years when he tees off on Thursday in the 148th edition of the Open Championship at Royal Portrush Golf Club.
McIlroy lagged well back of the leaders at the end of the first round in each of his past three Open Championship appearances, but sat atop the leaderboard after the opening round during his march to his lone victory at this event back in 2014.
Not surprisingly, McIlroy is also set as -250 chalk to be the top Irish player this weekend, outpacing second favourite Shane Lowry, who sports +450 odds despite failing to make the cut in his past four appearances at the event. Lowry has also missed the cut on five occasions this season, but turned in top-five performances in three of his past five outings, including an eighth-place finish at the PGA Championship as a +17500 wager.
Koepka, who has seen his British Open odds slip to +1000 since opening the week at +750, now also sits second to McIlory on the odds to be the first-round leader, pegged at +2000.
The 29-year-old has been dominant while winning four major tournaments over the past two years, including this year’s US Open victory as a +750 wager, and is set as a clear +450 favourite to be this weekend’s top American, outpacing both Dustin Johnson and Tiger Woods, who lag knotted at +700 at sports betting sites.
Now perched as the world’s top-ranked golfer, Koepka seized the early lead at the 2017 Open Championship. However, success at this event has been elusive, with Koepka cracking the top ten just twice in five career appearances.
A second-place finisher at last year’s British Open, Justin Rose sits as a +325 favourite to be the top Englishman this time around on the golf odds. Adam Scott is listed as a narrow +185 favourite to be the top Australasian player, narrowly edging out Jason Day at +200, while 2018 winner Francesco Molinari is a -350 favourite to be this weekend’s top Italian player
As well, the odds of a playoff being needed to determine an Open Championship winner for the first time since 2015 sit at a lengthy +300, while this year’s winner claiming a wire-to-wire victory is pegged as a +275 underdog.
