Two-time Olympic champion Shelly-Ann Fraser-Pryce and two-time World 200m champion Shericka Jackson officially got their bids to make it to the Paris Olympics underway by getting through to the semi-finals of the Women’s 100m on day one of the JAAA National Senior and Junior Championships at the National Stadium in Kingston on Thursday.

Fraser-Pryce, in her second race of the season, eased to a season’s best time of 10.98 to advance to Friday’s semi-finals as the fastest qualifier.

Tia Clayton ran a personal best 11.02 to also advance from Fraser-Pryce’s heat while Ashanti Moore ran 11.24 in third to also advance.

Jackson also looked in cruise control, jogging to a season’s best 10.99 to win her heat. Jodean Williams came agonizingly close to dipping below the 11-second barrier for the first time with a personal best 11.01 in second while Alana Reid also advanced with 11.20 in third. Niesha Burgher's 11.32 was also enough to take her through.

The third heat produced five semi-finalists with Natasha Morrison (11.12), Kemba Nelson (11.16), Shockoria Wallace (11.24), Briana Williams (11.25) and Lanae-Tava Thomas (11.27) all getting through to the semis.

Shashalee Forbes (11.03), Krystal Sloley (11.12), Tina Clayton (11.13) and Jonielle Smith (11.23) advanced to the semi-finals from heat four.

The semi-finals and final are scheduled for Friday.
