England's Paul Casey overcame chilly conditions and a sore throat to grab a one-shot lead on day one of the European Open in Germany on Thursday.
World number 17 Casey showcased his powerful driving and precise iron play on the third longest course on the European Tour to card a six-under-par 66, including five birdies on the last eight holes.
Austrian Matthias Schwab was Casey's closest challenger with an opening 67, one shot ahead of Scotland's Robert MacIntyre, Englishman Ben Stow and home favourite Max Rottluff.
Casey, who last won on the European Tour at the KLM Open in 2014, was pleased with his performance at Green Eagle Golf Course in Hamburg.
"It was a really good round of golf," he said. "Yeah sure, there were a few putts that slid by but that is such a difficult golf course. I can't explain how difficult that golf course is.
