The 87th-ranked wild card surprised five-time champion Roger Federer, 7-6 (5), 6-4 to win the Halle title for the second time in June, 2012. It was Haas' 13th career title and first since he won Halle in 2009. The former world No. 2 hadn't beaten Federer in more than a decade, losing nine straight matches, but snapped that skid against the six-time Wimbledon winner.
