SPLITTING RIVALS: Trinidad and Tobago’s Machel Cedenio leads home Colombian Jose Zambrano, left, and Jamaica’s Akeem Bloomfield, right, to win semi-final three of the Men’s 400 metres event at the World Athletics Championships in Doha, Qatar, yesterday. Cedenio clocked a season’s best 44.41 seconds ahead of Zambrano (44.55) as the top pair secured automatic qualification to the final, while Bloomfield (44.77) still advanced as one of two to progress through the “fastest loser” route.
