Hale eyes PB power boost

TEENAGE sprint star Jack Hale is confident he can use added size and power to nail an individual berth at the Commonwealth Games by running a personal best time.

Hale burst onto the scene as a 16-year-old in 2014 when he clocked 10.13 over 100m in Adelaide.

That time was achieved with an illegal tailwind, but he officially became the fastest Australian junior sprinter of all time when he clocked a PB of 10.21 in Germany in 2016.

Now 19, Hale had a quiet 2017 campaign after deciding to focus on training instead of competitions. Hale estimates he has put on between 5-8kg since March last year, and he hopes the extra power will help him slash his times in the 100m sprint. His progress will be put to the test when he fronts up for the Perth Track Classic at the WA Athletics Stadium tonight.
