Track cycling - men's keirin first round
The Netherlands' Harrie Lavreysen wins heat two with Jack Carlin picking up second - 0.361 seconds further back - to advance to the quarter-finals.
There was a nervy moment on lap two when Carlin's back wheel flicked out and almost caused a crash but he managed to steady himself and get back on track.
