AUGUSTA, Ga. — Rory McIlroy has set the mark. Now comes the hard part.

The World No. 2 and four-time major champion has to prepare for perhaps the most important day of his professional career. McIlroy shot a second consecutive 66 Saturday at Augusta National to lead the Masters by two shots at 12-under-par total. He’s searching for the final leg of the career Grand Slam for the 11th time, looking to join Gene Sarazen, Ben Hogan, Gary Player, Jack Nicklaus and Tiger Woods.

Trailing McIlroy is Bryson DeChambeau, McIlroy’s nemesis from the U.S. Open last summer at Pinehurst. DeChambeau drained a long birdie putt on the 18th hole Saturday here to sneak within two shots after driving it into the bunker off the tee. He birdied three of the last four holes too. The two men will be in the final pairing Sunday at Augusta National. Corey Conners and Patrick Reed will be in the penultimate group.

Here is a list of the pairings. Check back here soon when the tee times are available. The final group is expected to tee off at Augusta National around 2 p.m. local time.
