Robert Karlsson showed some form ahead of the Ryder Cup with a five-under-par 67 in the first round of the Mercedes-Benz Championship in Cologne. The Swede carded seven birdies and two bogeys at Gut Larchenhof to trail co-leaders Richard Finch and Jean-Francois Lucquin by a shot, easily the best display from the four team members on show in Cologne.

Spain's Miguel Angel Jimenez had six birdies but four bogeys and a double bogey in a 72 was matched by Irishman Graeme McDowell, while Denmark's Soren Hansen - the defending champion but another Ryder Cup rookie - returned a 73.

Karlsson, who made his cup debut in the record-equalling victory at the K Club in 2006, had been reported to be suffering from a neck injury after taking three weeks off.

But the 6ft 5in Swede reiterated that those reports had been wide of the mark after instantly returning to the sort of form which has brought him nine top-10 finishes this season - including eighth in the Masters, fourth in the US Open and seventh in The Open.

"I just took an extra week off after playing a lot of golf in the summer," Karlsson said. "I never had any injury and had no treatment. I just enjoyed three weeks with my family, although the kids having chicken pox meant I did not have much time for practice last week.

"It would be nice to win but mainly I am here to get going again after three weeks off.

"I'm usually quite good at getting back quickly and I'm very happy to have another three days to play (there is no cut this week) after not playing for so long."

Finch has failed to match Karlsson's consistency this season but has claimed two tournament victories after narrowly keeping his card at the end of last season.

The 31-year-old from Hull only secured his playing rights by finishing seventh in the final event of 2007 but won the New Zealand Open in December and then added the Irish Open in May - despite memorably falling into a river while playing his third shot on the 72nd hole.

"Even this morning I was looking at the scores from the first stage of the Qualifying School because I've got a few friends in that, and I did think it might have been me this time last year," Finch admitted after a round of eight birdies and two bogeys.

"To be here instead and shoot a good score and be in with a chance is great.

Damien McGrane is best of the Irish on two under after a 70, while Peter Lawrie joins McDowell on level par.

Dubliner Paul McGinley is a shot further back but Darren Clarke slumped to a four-over-par 76.
