Kingston - Reigning world champions Usain Bolt and Shelly Ann Fraser-Pryce are both entered in this week's Jamaican trials despite holding byes to the Beijing world championships.
Bolt, who has struggled to find form this season, will compete in the 100 metres as the world record holder seeks race shape. He will compete in both the 100m and 200m at August's world championships.
Fraser-Pryce, the year's co-fastest in the women's 100m, is entered in both sprints at the trials, which begin on Thursday.
Olympic double sprint silver medallist Yohan Blake, who returned to action this month after an 11 month injury layoff, also is down to contest both the 100m and 200m. – Reuters
