Here are the Odds as Rory McIlroy Eyes Historic 2025 Grand Slam

Michael Sciangula April 17, 20254 min read

Rory McIlroy made golf history on Sunday at Augusta National, becoming only the sixth golfer ever to complete the career Grand Slam with a thrilling victory at the 2025 Masters.

McIlroy was a hot pick on Hard Rock Bet, generating significant excitement in the sportsbook and helping numerous bettors cash in impressive tickets. Here’s a look at some of the standout wagers:

Best McIlroy Masters Tickets

  • $6,000 bet placed pre-tournament at +650 odds, earning a $45,000 win.
  • $11,764.71 bet after Round 2 at +325 odds, earning $50,000.
  • $2,000 bet placed pre-tournament (without Scheffler) at +525 odds, yielding $12,500.

It was a roller coaster weekend for McIlroy, prompting a handful of bettors to cash out on Saturday night and avoid the Sunday sweat. The following tickets punched out early, locking in a W at the expense of potentially maximizing profit:

  • One bettor placed a $1,000 bet on Rory to win the Masters at +650 which would have paid $7,500, but they took a $4,621.15 early cash out on Saturday night before the final round.
  • Another bettor placed a $1,315 bet on Rory to win @ +325 on Friday night after round 2 was in the books. They accepted a $3,592.77 cash out offer the following night, leaving about $2,000 on the table.

Grand Slam odds: Can Rory achieve the impossible?

With the Masters in hand, the spotlight now turns to McIlroy’s quest for an unprecedented single-season Major Grand Slam—something never achieved in golf’s modern era. While legendary Bobby Jones completed a single-year Grand Slam in 1930, his achievement came during the amateur era, featuring a different set of tournaments.

Hard Rock Bet offers exlusive odds on Rory’s quest:

  • Single-season Grand Slam (winning the PGA Championship, U.S. Open, and The Open Championship): 100-1 (+10000)
  • Winning at least two more majors: 14-1 (+1400)
  • Winning one more major: +175

Rory Grand Slam Odds

A High-Stakes Believer

Back in March, one particularly bold New Jersey sports bettor at Hard Rock Bet made a series of smaller wagers on McIlroy, combining multiple Rory Grand Slam parlays with McIlroy’s victory at The Players Championship (which he secured in a thrilling playoff against J.J. Spaun).

If that wasn’t enough, every ticket also includes a sixth bet that could be anything from a college basketball moneyline to a baseball future. In total, the bettor is still live for more than $6 million – most of which hinges on the Grand Slam.

PGA Championship betting comes into focus

The next chapter in this historic run begins at the PGA Championship (May 15-18) at Quail Hollow in North Carolina. Currently, McIlroy is listed at +475, narrowly trailing favorite Scottie Scheffler (+450).

With the 2025 season heating up, all eyes — and a few significant wagers — are on Rory McIlroy as he aims to rewrite golf history once again.
