A four-stroke lead is always significant, but in the case of Rory McIlroy at the British Open, it's the steady dominance he's put on display with back-to-back rounds of 66 rather than just the leaderboard gap that make him a substantial favorite entering Saturday's play.
McIlroy has been on top of his game through two rounds, birdieing six of eight par-5s and averaging 333 yards off the tee. Bookmakers see McIlroy's four-stroke edge on Dustin Johnson - and his six-stroke edge on the rest of the field - as strong reason to back McIlroy into the weekend.
At 2-3, McIlroy's odds (per Bovada) implied a 60 percent win probability, while Johnson's second-best odds of 6-1 imply just a 14 percent chance at making a late surge in Merseyside.
The table below shows the 10 golfers with the best odds, as well as the odds for some other notable names:
