The changing of the guard in the men’s 100m could be completed on Friday evening at around 8:55 pm following the finals on the second day of the Jamaica Athletics Administrative Association (JAAA) National Championships at the National Stadium.

All things being equal, and if all the contenders show up ready to run fast, the three men to represent Jamaica at the World Athletics Championships in Budapest, Hungary, in mid-August could all be under age 23.

While not discounting the experience of 33-year-old Yohan Blake, who has shown over the past two years that he still knows how to be ready in time to make national teams, there is a handful of juniors knocking at the door and ready to make their mark.

Blake rolled back the clock a year ago to win the event at the National Championships, but it is his namesake Ackeem Blake who has set the pace with four races under 10.00 seconds and wind legal topped by a personal best 9.89 seconds.

The former Merlene Ottey High runner was third last year, his first full season in the seniors and went on to make it to the semi-finals at the World Championships in Eugene, Oregon.

A year later the NACAC Open champion could be ready to challenge for the national title as well as his first major global final.

Standing in his way could be Oblique Seville, who was fourth at the World Championships last year and who it is reported is over an injury that interrupted his preparation.

Seville has raced only five times so far this year, including two races at the Miramar Invitational and Adidas Atlanta City Games, but is unbeaten with a season’s best 9.95 seconds.

There are significant expectations from two schoolboys, Kingston College’s Bouwahjgie Nkrumie and Herbert Morrison’s DeAndre Daley who some expect to force their way onto the team.

Nkrumie has not raced much since his blistering national Under-20 record 9.99 seconds at the ISSA Boys Champs after pulling up in the first round of the Carifta Games in the Bahamas.

Since coming back from the injury he has run twice, clocking 10.42 seconds and 10.34 seconds, and it will be seen whether he has fully recovered.

Daley on the other hand has lowered his personal best 10.08 seconds, making him the second-fastest Jamaican ever at age 18 and under the guidance of coach Claude Grant, he could run even faster this weekend.

Despite a relatively low number of just 25 men entered for the 100m, down from as many as 70 a few years ago, there will be no shortage of contenders for places on the team to Budapest.

Thirty-year-old Julian Forte, last year’s 200m champion Andrew Hudson, Ryiem Forde, Kadrian Goldson and Michael Campbell will all be hoping to first get to the final and then stake a claim for the top spots.
