Overnight leader Niall Kearney carded a round of 69 to sit two shots off the lead at the Dutch Open as Graeme McDowell charged up the leaderboard in Cromvoirt.

Kearney, who began the second round on seven under, a shot ahead of Denmark's Martin Simonsen and Germany’s Maximilian Kieffer, racked up four birdies and a boogey to reach 10 under for the tournament.

McDowell shot a round of 66, comprising of seven birdies and a solitary bogey, as the Portrush man soared to a share of seventh on seven under after opening with a round of 71.

"It was a little better today," the 2010 US Open winner said. "I improved on the two areas that I needed to, which were getting the ball in play off the tee and feeling a bit better on the greens.

"After a couple of months on the couch, I am obviously very pleased with a lot of the things I am doing. My swing and iron play feels particularly good, and this is a key iron play golf course.

"The fairways are wide, if you get it into them you are faced with some tricky iron shots into these pin positions, so pretty happy with that. I'm going to need a couple of low ones to get a win this weekend but it’s nice to be in touch."

Kristoffer Broberg's sizzling 64 propelled him to top spot on eight under after the Swede had opened with a 68.

"I played really well today," Broberg said. "I started off with three straight birdies and then I hit a good shot on 13, that tough par three there, but I missed a short one and then birdied 14.

"I hit some bad shots and some really good shots but my putter is smoking hot, so I am playing some decent golf.

"I am taking it one shot at a time. I have been struggling all year with injuries, so it is nice to be playing good again.

"I was home for a month so saw an optician for my right eye and they saw something, so I have a contact lens on that eye so now I can see the putts on the line. I am rolling it pretty good so happy with it."

Denmark's Marcus Helligkilde and Belgium's Thomas Detry share second spot on 11 under after both men carded rounds of 66, with Kieffer alongside Kearney on 10 under.

Cormac Sharvin and James Sugrue survived the cut, while Gavin Moynihan and Paul Dunne are heading home after disappointing tournaments.
