Tokyo:Avinash Sable shattered his own 3000m steeplechase national record but failed to qualify for the final while sprinter Dutee Chand produced a below-par performance to make an exit from the Olympic Games here on Friday.
MP Jabir also brought up the rear in men's 400m hurdles as the Indians made a disappointing start to their athletics campaign.
The 26-year-old Sable failed to qualify for the final despite clocking a better time than the top three in another heat race.
He clocked 8 minutes 18.12 seconds in heat number 2 to finish seventh and better his earlier national record of 8:20.20 that he had set during the Federation Cup in March.
But he was unlucky to miss the finals cut as only the top-three finishers from each heat gain automatic entry. The top-three from heat number 3 ran in slower time than him.
Fifteen athletes -- the best three in each of the three heats and the next six fastest athletes across all the qualifying heats -- qualify for the final.
Sable ended seventh next best across all the qualifying heats and 13th overall.
