Paul Hession set a new Irish record for the 100m at the EAA meeting in Kalamata, Greece yesterday.
Hession clocked 10.28 for the distance, which beat the previous mark of 10.35 held by Paul Brizzel and Gary Ryan in 2000.
Hession, 23, completed at sprint double at the event by winning the 200m race in 20.67.
Elsewhere at the event, Luis Tsatoumas produced a world-leading 8.66m leap in the long jump.
Meanwhile, Tyson Gay was denied the world 100m record by a following wind just over the legal limit of two-metres-per-second at the Reebok Grand Prix in New York.
Less than a fortnight after achieving a wind-assisted mark of 9.79sec in Carson, the 24-year-old was again in sensational form clocking a time of 9.76sec.
That bettered Asafa Powell's world record figure of 9.77sec, which the Jamaican star has achieved on three occasions, but the tailwind was 0.2sec above the permitted limited.
