Guam's Pilar Shimizu has swam a personal best time in the women's 100m breaststroke heats on day three of the London Olympics.
The 16 year old finished second in the opening heat in a time of 1.15.76, fulfilling her aim of swimming under one minute 16 seconds.
Shimizu says she has never been as nervous as she was before her race.

Fonua had been hoping to swim under a minute and two seconds but managed 1.03.65, which, while enough to win the opening heat, was slower than every time in the other five heats.
