Six players share the lead after the opening day of the Nordea Masters on Thursday.
Andrew Johnston, Clement Berardo, Florian Fritsch, Marc Warren, Scott Henry and Sebastien Gros all shot 5-under 67 on the Bro Hof Slott course outside Stockholm.
Lee Westwood, a three-time winner of the tournament, was one shot behind after six birdies and two bogies in his opening round.
"I'm starting to hit the ball really well and seeing the flight on the shots that I like and on the greens I rolled the ball really well," Westwood told the European PGA tour website.
World No. 6 Henrik Stenson was five strokes behind the leaders, finishing the day on par.
