Nesta Carter
Bolt was a member of the silver medal relay team with Asafa Powell, Marvin Anderson, and Nesta Carter in the 4×100 metres relay. Jamaica set a national record of 37.89 s. Bolt did not win any gold medals at the major tournaments in 2007, but Mills felt that Bolt's technique was much improved, pinpointing improvements in Bolt's balance at the turns over 200 m and an increase in his stride frequency, giving him more driving power on the track.
