KINGSTON, Jamaica (CMC) — Jamaican Yohan Blake is beaming with confidence after his stunning 19.78 run at Thursday's 10th IAAF Diamond League meeting in Monaco's Stade Louis II.

The 20-year-old carved out the time as he sped to second place behind winner American Tyson Gay who clocked 19.72 seconds, and believes the performance has set him up to shock the world.BLAKE ... there is no word to explain how I feel

"I know my potential because my coach (Glen Mills) believes in me and I am not surprised with [the] run," said Blake.

"I said to persons before the race that I was going to shock the world, and that is what I am going to do," said Blake, who narrowly lost to American Gay in a close finish.

Blake improved on his personal best of 20.60 to pass Donald Quarrie (19.82) as the second fastest Jamaican behind Usain Bolt, who has the world record of 19.19.

He is also third on the Caribbean list, only behind Bolt and Trinidad & Tobago's Ato Boldon (19.77).

Known more for his 100 metres exploits, Blake said he received a call "out of the blue" from Mills telling him to attempt the half lap.

"He said he knows how good I am and told me I should just go out there to run," Blake explained.

Now the 12th fastest man of all-time, Blake said "there is no word to explain how I feel ..."

He is scheduled to run one more 200m, two 100m and a sprint relay during the remainder of the season.
