THE selectors of the Jamaica team to the 13th IAAF World Championships to be held later this month in Daegu, South Korea, could have some more work to do before finalising the team after Isa Phillips ran a season’s best 48.94 seconds to win the 400m hurdles at a low keyed meet in Mannheim, Germany yesterday.

Phillips’ time is the best by a Jamaican so far this season and 14th best in the world, eclipsing the 49.03 seconds done by national champions Leford Green at the Central American and Caribbean Games in Mayaguez, Puerto Rico last month and is the A standard for qualification for the World Championships.

The Jamaica Athletics Administrative Association (JAAA) has until tomorrow midnight Central European time (5:00 pm Jamaica time) to submit their final list of entries to the IAAF for the event that starts on August 27.

Phillips finished fifth at the JAAA/Supreme Ventures National Senior Trials in late June behind Green and Josef Robertson — who both have the A standard — Roxroy Cato who has a B standard, and Danny McFarlane, who also has an A standard.

Since then McFarlane, who was chasing a record 10th appearance at a World Championships, withdrew his name from consideration for the team.

According to the selection criteria laid out by the JAAA, athletes placing in the 1st to 3rd positions in all events will be selected if they have attained the qualifying A standard for the event.

The selection criteria also states that all athletes must maintain and prove their competitive fitness up to the time of the final entry date for the competition.

Each IAAF member country is allowed one B standard per event, according to the IAAF rules.
