LONDON, England:

Jamaica will be hoping to add to its medal tally today as the women's 4x100m relay team takes centre stage at the Olympic Games in London.

A team of Samantha Henry-Robinson, Sherone Simpson, Schillonie Calvert and Kerron Stewart on anchor, qualified for today's final, which is set for 8:40 p.m. (2:40 p.m. Jamaica time).

It was not a smooth qualifying run as the Jamaicans had to settle for second place with a time of 42.37, behind Ukraine, 42.36, after an untidy baton change between Simpson and Calvert on the backstretch.

The Jamaicans, who are expected to add 100m gold medallist Shelly-Ann Fraser-Pryce and bronze medallist Veronica Campbell-Brown to the team for the final, will start in lane six, but Stewart, who should retain her place, believes the team can do well once there is trust among the members.

"Safety is always first but tomorrow we will just have to go out there and have fun and importantly, we have to trust each other," said Stewart.

baton mishap

The Jamaicans did not finish the final at the last Olympics after a baton mishap and Stewart is happy that despite the poor changes yesterday in qualifying, they managed to advance.

"We are in the finals and if you are not in the finals you don't have a say so right now we have a pretty good say," Stewart said.

"I mean, when you have four people running together who don't do baton passes a lot and who don't run together a lot you have to expect stuff like this so it's not about getting a lot of practices, it's about competing together with the stick on the track.

Also today, the women's 4x400m relay team will try to qualify for tomorrow's final.

Jamaica will compete in heat one with Ukraine and France as the main threats with the team expected to be selected from the relay pool of Dominique Blake, Shereefa Lloyd, Shericka Williams, Christine Day, Rosemarie Whyte and Novlene Williams-Mills.
