STOCKHOLM, Sweden — Swedish amateur Robert Karlsson shot a 5-under 67 on Thursday to share the lead with countryman Alexander Noren and Jaco Van Zyl of South Africa after the first round of the Nordea Masters.
The 22-year-old Karlsson, one of only three amateurs in the tournament, had seven birdies and double bogey on the 7,603-yard Bro Hof Slott course — the longest on the European Tour this year.
Noren made eight birdies, one bogey and a double bogey, while Van Zyl had six birdies and a bogey.
Bubba Watson shot a 71 and Dustin Johnson, who shared second place in the British Open on Sunday, finished with a 73.
The tournament changed its name to Nordea Masters from Scandinavian Nordea Masters this year.
