After three men and three women seeded players fell on day 1, it was the turn of three other gentlemen and six more women seeded players exiting in the first round on Tuesday. Barring this breed of first round losers, most men and women top stars stayed on course. World no.1 and second-seed Rafael Nadal had an early scare, when he dropped a set before beating Slovak Martin Klizan and Jo-Wilfried Tsonga fought to survive a five-set battle against Austrian Jurgen Melzer.
