Rory McIlroy has set up the possibility of a special Sunday for himself and girlfriend Caroline Wozniacki.
The 22-year-old Northern Irishman fired a second-round 65 to move into contention at the KLM Open in the Netherlands on five under par at halfway.
Tennis world number one Wozniacki, meanwhile, is two wins away from joining him as a US Open champion.
After all the rain delays in New York she will now play her semi-final against Serena Williams, with the final being pushed back to Sunday.
There has also been bad weather at Hilversum and that meant McIlroy had to play 27 holes as the tournament tried to make up for time lost.
An opening 70 left him deep in the pack five behind overnight leaders Simon Dyson and Marcel Siem, but as they started their second rounds late in the day he was alongside them and only two behind Indian Shiv Kapur in the clubhouse.
World number two Lee Westwood is also in the hunt and would have matched his Ryder Cup team-mate’s two rounds but for a late three-putt bogey.
McIlroy’s first priority after he finished was to make sure there were no more ants on him.
His final drive finished close to an ant-hill and, although he was able to move his ball away and had a much easier shot as a result, he said: “I still feel there are some going up my legs.
“I don’t feel I drove the ball particularly well. There were a couple of loose shots and I got some lucky breaks.”
Like McIlroy, Westwood had four birdies in seven holes on the back nine, but his only gain on the outward half was a two on the short fifth and his dropped shot came two holes later.
Kapur’s 67 put him one ahead of Scot Gary Orr and South African James Kingston before twice-winner Dyson and Siem made it a four-way tie for second with an early birdie each.
They were unlikely to finish their second rounds before nightfall, but a tournament held up first by vandalism to four greens and then by flooding should be back on track.
Welshman Stephen Dodd took over at the top with a dazzling run. After an opening birdie on the ninth he reduced the back nine to a mere 30 strokes with an eagle and three more birdies.
At eight under, Dodd led by one from Kapur and by two from Orr, Kingston and Siem, while Dyson was one further back after seven holes along with McIlroy and Swede Oscar Floren.
The big surprise was that defending champion Martin Kaymer was heading out, double-bogey sixes on the sixth and seventh taking him to six over.
