NEW YORK (Reuters) -Madison Keys said the nerves she experienced in her first U.S. Open appearance as a Grand Slam winner proved "paralysing" after the sixth-seeded American was sent spinning out of the opening round in New York on Monday.

Keys notched up a staggering 89 unforced errors and made 14 double faults in her 6-7(10) 7-6(3) 7-5 defeat by Mexican Renata Zarazua in front of stunned spectators on Arthur Ashe Stadium to become the highest seeded casualty of the women's draw so far.
