Xavier Malisse (born 19 July 1980) is Belgian retired professional tennis player. Born in the north-western Flemish city of Kortrijk and nicknamed "X-Man", he is only one of two players from Belgium (the other being David Goffin) to have been ranked in the top 20 of the ATP tour, with a career-high singles ranking of World No. 19. Using only the above description and what you know about the world, "Xavier Malisse was born in the summer of 1980." is definitely correct, incorrect, or inconclusive?
