Former Ryder Cup star Sandelin shot an eagle and four birdies for a bogey free-66, while Parry carded a second-round five under par 67 thanks to two closing birdies at the Golf de Joyenval, Chambourcy course near Paris in France.
“I’ve been playing much better the last three weeks – and this week especially,” said Sandelin. “I haven’t had too many bad shots this week so far, so if I can keep it
going on like this, I think I will be a happy man at the end of the tournament. ”
Sandelin is 168th on The Race to Dubai and needs to climb into the top 115 to avoid a return to Qualifying School, while Parry is just shy at 116th.
“It was good,” said Parry. “I’ve been playing well for the last couple of weeks, at least trying to put it all together, putt well and hit it well, which is a bit more like it for the first two days.”
The pair are three shots clear of France’s Julien Guerrier, Australia’s Richard Green and Madeira Islands Open winner James Morrison.
Sandelin took over atop the leaderboard from compatriot Johan Edfors, a former British Masters Champion, who sunk 10 birdies on Thursday, equaling the lowest round of the European Tour this season with a score of 61.
Ryder Cup player Padraig Harrington, who was second after Edfors seven shots off the pace, was down in a tie for 58th, 11 shots off the lead at the halfway stage. Three-time major winner Harrington hit a second round 74 and avoided the cut by enjoying three birdies in his last six holes.
