ST. ANDREWS, Scotland — It looks like another day for going low at the Old Course.

The morning starters are again playing under partly sunny skies with only a light breeze, setting up a repeat of Sunday’s third round when the scoreboard was filled with red numbers. New Zealand’s Ryan Fox posted a 5-under 67 playing in the first group. South African Branden Grace is 6 under through 13 holes.

Of course, all eyes are on Jordan Spieth, who’s looking to pick up the third leg of the Grand Slam. He’s one shot off the lead.

The 21-year-old Texan stopped to sign a few autographs Monday before heading to the practice range to begin preparing for his shot at history.

He’s already won the Masters and the U.S. Open, and he’s trying to join Ben Hogan as the only players to win the first three majors of a year.

If he can win the Open, Spieth will go to next month’s PGA Championship trying to become the first player to win the modern version of the Grand Slam.

Spieth tees off at 2:20 p.m. in the next-to-last group with co-leader Jason Day.

Day is tied for the top spot with Louis Oosthuizen and amateur Paul Dunne, who will tee off in the final group at 2:30 p.m.
