ST. ANDREWS, Scotland (AP) -- Jimmy Mullen and Anthony Wall shared a one-stroke lead after the second round of the Alfred Dunhill Links Championship on Friday.
Overnight co-leader Mullen, who is making his professional debut, added a 3-under 69 at St. Andrews to his opening 64 at Kingsbarns to finish 11 under alongside fellow Englishman Wall.
The tournament is split between three courses, with players alternating between St. Andrews, Kingsbarns and Carnoustie.
''I'm just out there trying to enjoy it and learn really, and to be top of the leaderboard I can't really explain it,'' said Mullen, who had five birdies and two bogeys on the Old Course.
