Shanoya Douglas ran a blistering personal best 22.59 seconds (0.4m/s) to win the girls’ 19-and-under 200m race, the third-fastest- ever by a Jamaican junior, as the Jamaica Athletics Administrative Association national junior championships came to a close at the National Stadium on Sunday.

Romario Hines also had a personal best to win the boys’ equivalent.

The four-day championships, which produced a number of outstanding performances, will be used to select the team to represent the country at the World Athletics Under-20 Championships to be held August 27-30 in Lima, Peru.

Douglas, who won the girls 200m/400m double at the Inter-secondary Schools Sports Association (ISSA) Girls’ Championships in March, smashed her previous best of 23.16 seconds set at the Carifta Games held in Grenada in April. She trails only Briana Williams (22.50) and Brianna Lyston (22.53) as the fastest Jamaican junior.

She also moved into second place in the world rankings for Under-20 girls this year, behind American JaMeesia Ford’s 22.08.

The Muschett High student prevented United States-born Skyler Franklin (23.16) from taking the 200m/400m double. Sabrina Dockery placed third in 23.24.

Hines, who was a finalist in the 100m on Friday, ran a personal best 20.78 (0.8m/s) under his old 21.01 and should be accompanied by 100m champion Gary Card who ran with the senior men in the 200m, clocking a personal best 20.50.

Earlier in the day, Franklin, who was competing at the National Stadium for the first time, won the 400m in 51.99, well ahead of Abigail Campbell (53.42) and Shanque Williams (53.92).

Jabari Matheson of William Knibb was a surprise winner in the boys’ 400m, running a lifetime best 46.64, beating Kemarrio Bygrave (46.80) and Javaughn Pinnock (46.98).

Richard Hall was a close winner in the 110m hurdles, clocking 13.37 (0.2m/s) the same time given to Daniel Beckford, while Daniel Clarke was third in 13.44.

The 100m hurdles final was also close with Habiba Harris winning in 13.06 seconds (0.3m/s), just edging Shania Myers (13.08), with Tonie-Ann Forbes placing third with 13.12.

Rasheed Pryce won the boys’ 800m in 1:54.79 minutes, ahead of Schevorn Wardlow (1:55.48) and Joseph Parks (1:55.92).

Kitania Headley won the girls’ two-lap race in 2:09.77, ahead of Carlene Temple (2:10.75) and Shaneal Clarke Giddings (2:11.75).

In the absence of world record holder Jaydon Hibbert, Chavez Penn won the boys’ triple jump with 15.79m (-1.0m/s). Romario Lewis was second with 14.77m (0.2m/s) and Euan Young took third with 14.66m (-0.4m/s).
