KINGSTON, Jamaica -- Demisha Roswell’s patience paid off after she ran a brilliant personal best 12.40 seconds (0.7m/s) to win the 100m hurdles title on Sunday’s final day of the JAAA national championships at the National Stadium, beating a quality field. Her time, which beat her previous best of 12.44 seconds, ranks her fourth in the world and joint fifth best with Janeek Brown on the Jamaican all time list. Roswell held her form under pressure to beat pre-championships favourite Megan Simmonds-12.47 seconds and Kerrica Hill, who was third with 12.67 seconds.
