Dwain Chambers of Britain again failed to make the Olympic qualifying time, despite winning the 100 meters event at the Memorial Primo Nebiolo in Turin.
Chambers was more than a tenth of a second off the required time of 10.18 seconds, winning in 10.29.
Suwaibou Sanneh was second, 0.1 seconds behind, with Gerard Kobeane third in 10.57.
Chambers has struggled to get back to his best after serving a two-year doping ban. He was a bronze medalist at the 1999 world championships with a time of 9.97.
