First Grand Slam appeareance for Florin Mergea, former #1 junior in both singles and doubles, winner at Wimbledon(both single and doubles), finalist at Australian Open and so on. He was injured for 3 years and he returned to tennis in late 2011 without any WC, playing only futures at the beggining and then challengers.
Injured for three years straight? Really? I just sort of assumed he hung up his racket as he wasn't getting great results.
