Dyson - has the edge on day one.

An in-form Simon Dyson shares the lead at the KLM Open on a day that saw delays due to overnight vandalism and heavy flooding.

Dyson shot a first-round 65 at Hilversumsche Golf Club in the Netherlands to lead by one stroke alongside Germany's Marcel Siem - though half the field are yet to complete their first rounds after four greens were damaged by vandals overnight, leading to a 45-minute delay at the start of play to complete repairs, and heavy flooding on the course led to a further three and a half hours of play being lost later in the afternoon.

"That's probably the wettest course I've ever played," said Dyson, a two-time winner (in 2006 and 2009) of the KLM Open already, after his round.

It's been a good year for the Englishman, who currently lies 10th on the Race to Dubai, after victory at the Irish Open earlier in the season and a string of good performances elsewhere.

"My best finish (in the Race to Dubai) is eighth and I would love to beat that."

Dyson played his front nine in a reasonably sedate even-par, but then came alive on the back, carding four birdies, an eagle and a lone bogey to finish on five under for the tournament alongside Siem.

In contrast, Siem is without even so much as a top-10 finish so far this year, and still has work to do for the remainder of the season if he's to keep his card. He currently lies in 104th place on the Race to Dubai.

Like Dyson, Siem also eagled the long 12th and added two birdies apiece on each nine, as well as a lone bogey at the 10th.

England's Robert Dinwiddie lies alone in third, one shot off the pace after a 66, while two more Englishman, Oliver Wilson and David Lynn, share fourth place on three under with Dane Anders Hansen and Jin Jeong of Korea, who had only completed 10 holes of his first round.

Defending champion Martin Kaymer, who had been so enthused about his game after his second place finish in Switzerland last week, lookd out of sorts as he limped to four-over 74.

The two other big guns at the tournament, Rory McIlroy and Lee Westwood, were among the later starters and were one over and even par through eight holes respectively before bad light brought an end to the day's proceedings.
