GLENEAGLES, Scotland -- Ricardo Gonzalez shot a second straight 7-under 65 Friday, giving him a one-shot lead after two rounds of the Johnnie Walker Championship.
The 352nd-ranked Argentine birdied three of his opening seven holes before finishing with five straight birdies. That put him at 14-under 130 on the PGA Centenary course that is hosting the Ryder Cup in 2014.
Austria's Bernd Wiesberger, who shared the first-round lead with Gonzalez, shot a 66 that left him alone in second place.
The 43-year-old Gonzalez is a four-time winner on the European Tour, with his last victory in 2009. Since then, both his parents died.
"The last two years have been very difficult personally," he said. "So if I win I would like to dedicate it to my mother and father. That's my target this week."
Mark Foster, who lost in a playoff at Gleneagles in 2011, added a 67 to an opening-round 66. He was tied for third with fellow Englishman Tommy Fleetwood (65).
Brooks Koepka of the United States was fifth, four shots behind. He had a second-hole eagle to go with four birdies in a 66. Koepka is assured full European Tour membership in 2014 after winning three times this year on the secondary Challenge Tour.
England's Paul Waring equaled the Centenary course record with a 63, but is tied for 19th place because of a 75 Thursday.
