First-round score for England’s Paul Casey, who led the Porsche European Open on Thursday at Green Eagle Golf Courses in Hamburg, Germany. Casey, 42, a 13-time winner on the European Tour, offset one bogey with seven birdies to post a 6-under round in windy, rainy conditions. “The score doesn’t really do it justice,” said Casey, a four-time Ryder Cup player. He called it “one of the finest rounds of golf I’ve played this year.” Casey hasn’t won on his home tour in five years, but he won the PGA Tour’s Valspar Championship in 2018 and 2019. Austria’s Matthias Schwab shot 67 to stand alone in second. Local favorite Max Rottluff joined Scotland’s Robert MacIntyre and England’s Ben Stow at 68. Americans Xander Schauffele (73) and Patrick Reed (74), the highest-ranked players in the field, at Nos. 9 and 16, respectively, in the Official World Golf Ranking, failed to break par (scores).
