I would like to know which qualifier it is. On the ATP website, 6 players have this name. QUALIFIER QUALIFIER10 seems the strongest one.
QUALIFIER QUALIFIER10 is a mug and has done nothing since it burst onto the scene at the 1969 Paris Indoor Tournament. QUALIFIER QUALIFIER1 beat it in straight sets in Hamburg in 1969 and then QUALIFIER QUALIFIER10 gave a walkover next time they faced each other two months later in Barcelona.
