"We waited hours," said Otte at Sky and joked: "I was broken three times." According to Daniel Altmaier, Otte is the second German professional at the sandplace event this year, who mastered his opening hurdle. Routinier Philipp Kohlschreiber failed due to Altmaier and Max Hans Rehberg also missed a victory.
