HILVERSUM, Netherlands (AP) - Stephen Dodd of Wales and Marcel Siem of Germany shared the lead on 8 under at the KLM Open but have yet to complete their second rounds after darkness forced an early end for 78 players on Friday.

Dodd played 13 holes of his second round in 6 under, opening with a birdie at the par-4 No. 9, adding an eagle 3 on No. 12 before closing the back nine with three more birdies.

Siem followed up his 65 on Thursday by shooting 3 under after 11 holes of his second round at the tree-lined Hilversum Club.

Shiv Kapur of India, who has never won on the European Tour, shot a 3-under 67 to take the clubhouse lead at 7 under.

"I've been driving the ball really well and on this course there's a big premium on hitting a lot of fairways," Kapur said.

U.S. Open winner Rory McIlroy was two shots behind Kapur after surging into contention with a 5-under 65 in his second round.

After taking to the course early to complete his rain-delayed, level-par first round, McIlroy had a bogey 5 on the first hole of his second round before reeling off six birdies to be tied for seventh.

"I don't feel I drove the ball particularly well," McIlroy said. "There were a couple of loose shots and I got some lucky breaks."

World No. 2 Lee Westwood was tied for ninth at 4 under.

Defending champion Martin Kaymer was 6 over for the tournament with six holes to play Saturday and looked likely to miss the cut.

Kaymer appeared to be fighting his way back from an opening-round 74 by birdying two of his first five holes in his second round, but double-bogeyed Nos. 6 and 7.

The projected cut is at par.
