Smyth sets new world record for gold
Jason Smyth crushed the field to win gold in the T13 100m
Ireland's Jason Smyth produced a performance training partner Tyson Gay would have been proud of by retaining his Paralympic 100 metres title in a new world record.
The 25-year-old, who has trained alongside the joint second fastest man in history in Florida over the last three winters, raced away from the rest of the field to take the T13 crown in 10.46 seconds.
The fastest Paralympian in the world spread his arms wide in celebration as he crossed the line, winning by a margin not even Usain Bolt is accustomed to.
The reigning champion could have been competing for Great Britain such was the cheer when he was introduced to the crowd and victory was never in doubt as he won by over half a second from Cuban Luis Felipe Gutierrez.
Smyth had already broken the world record in the heats with a 10.54secs run.
Jordan Howe finished seventh in the T35 100m final in 13.69s, while Hazel Robson was fifth in the T36 200m final in 32.46.
Stef Reid and Sophie Kamlish both made it through to the final of the T44 100m.
Michael McKillop made it double gold for Ireland by storming to victory in the T37 800m in a new world record time of 1:57.22.
The 22-year-old finished more than four seconds ahead of Tunisia's Mohamed Charmi.
Hollie Arnold was fifth in the F46 discus with a best effort of 36.27m, a new personal best.
