Former finalist Marcos Baghdatis has retired from his third-round match at the Australian Open because of a reported groin injury.

Baghdatis was trailing Saturday's match 6-7 (5), 6-2, 6-1, 4-3 when went to the net and shook hands with No. 11-seed Jurgen Melzer of Austria. The 21st-seeded Cypriot player pulled out of the Sydney International last week with the same injury.

Roger Federer beat Baghdatis in four sets in the 2006 Australian Open final.
