Sweden\'s Joel Sjoholm, nattily dressed in plus-fours, grabbed a two-shot lead at the halfway stage of the BMW International Open on Friday. The 27-year-old Chilean-born player, who was adopted by a Swedish couple when he was three months old, carded two eagles and four birdies in a second round 66 to reach 11 under par. That was two better than overnight joint-leader Fabrizio Zanotti, former Ryder Cup star Paul McGinley and English pair Danny Willett and Chris Wood. \"Now I saw that I\'m up there, and of course it\'s going to be a new situation for me,\" said Sjoholm, the world 306. \"But then I watched a lot of Euro 2012 the last two or three weekends, I\'ve seen what happens after four or five minutes, and I\'m happy to be on top at the moment - but I would rather be on top on Sunday. \"I\'m just enjoying this so much, I don\'t really think too much about it. It\'s just a great feeling and a fantastic tournament. I\'ve always played here in Germany, and it was good to play well at the new venue.\" Zanotti had shared the first-round lead with Marcus Fraser, but managed only a 71 while the Australian fell five behind with a 74. Germany\'s Martin Kaymer, the highest-ranked player in the field, missed the cut, but 54-year-old compatriot Bernhard Langer shot 67 to be five under.
