Lahiri leads in Switzerland
India's Anirban Lahiri fired two eagles on the back nine to take a two-shot lead after day one of the Omega European Masters.
The 26-year-old, who started at the 10th, made a three at the 597-yard 14th, birdied the 15th and then holed his approach to the par-four 18th to turn in 31 at four under.
Further birdies at the first, second, sixth and ninth completed a superb 63 and saw him end the day two in front of former champion Miguel Angel Jimenez and English duo Paul Casey and Tommy Fleetwood.
"Halfway through the round, I really got it going," said the man from Bangalore, who has yet to record a top ten finish on The European Tour but has won three times on the co-sanctioning Asian Tour.
"I didn't really get off to a great start. I was one-over through four holes and a couple of eagles on the back nine got my momentum going and I'm happy I managed to focus all the way through."
Lahiri is still nursing a twisted knee after falling awkwardly four weeks ago.
He explained: "I've a history with my knee as I tore my ACL when I was 15 so it was tough.
"I didn't hit balls for 15 days. Monday was probably my fourth round in a month. I came in with no expectations and just wanted to enjoy my golf and that's probably what's happening out there today."
Jimenez, the 2010 winner and a regular in the top 10 in this event, fired in six birdies during his 65 with his only dropped shot coming at the 191-yard third.
Casey's 65 was boosted by an eagle at the seventh before his momentum was halted by a bogey six at the 15th. However the Irish Open champion got that shot back straight away with a birdie at 15 and holed a 12 foot putt at the last.
Fleetwood, winner of his maiden European Tour event at the Johnnie Walker Championship at Gleneagles a fortnight ago, bogeyed two of his first seven holes but reeled off six successive threes to play a stretch of six holes between the 17th and fourth in six-under to rocket up the leaderboard.
Thomas Bjorn, the 2011 winner, shares fifth place after a 66 and told Sky Sports: "It was all right. It was a bit off here and there but the short game saved me.
Good day's work
"There are a lot of opportunities on the course. I made five birdies and no bogeys and that is a good day's work," added the Dane.
Ryder Cup star Francesco Molinari carded a two-under 69 late in the day although that was eclipsed by his captain at Medinah, Jose Maria Olazabal, who returned a fine four-under 67.
Also on two-under are Darren Clarke - temporary reunited with former caddie Billy Foster this week - and last week's Welsh Open winner Gregory Bourdy.
But it was a day to forget for Chinese amateur Wo-cheng Ye, who only turned 13 on Monday. He finished seven over after three double bogeys in his first four holes.
