Ireland's Niall Kearney defied his lowly world ranking of 599 to open up a two-shot lead at the half-way stage of the BMW International Open in Munich, Germany, on Friday. Kearney played the final two holes of his weather-delayed first round in one under par in the morning to complete a flawless 65, before adding a second round of 68 to reach 11 under par. Viktor Hovland, Bernd Wiesberger, Masahiro Kawamura, Adrien Saddier and Jorge Campill share second place on nine under, with US Open runner-up Louis Oosthuizen and two-time major winner Martin Kaymer part of a group two shots further back.
