Dev Meena and Kuldeep Yadav improved the pole vault national record to 5.45m during the Federation Cup on day three of the event.
Dev Meena cleared 5.42m to first break the previous national mark of 5.41m. Kuldeep Yadav then cleared 5.45m to set a new record before Meena equalled the height.
Both athletes, who train together at the Madhya Pradesh Academy under coach Ghanshyam Yadav, failed to clear 5.50m. Meena won gold on countback.
The pair has now improved the national record three times this year. They have both cleared the Commonwealth Games qualification mark, though final selection remains with the committee.
