Michael Norman broke 10 seconds again as he won the 100m at the Internazionale Citta' de Padova meeting in Italy on Sunday (5 September).
Meanwhile, Sha'Carri Richardson remains without a win since a failed drug test for marijuana invalidated her win at the U.S. Olympic Trials as she just failed to reel in fellow American Javianne Oliver in the short sprint.
Norman clocked 9.97 to beat Marvin Bracy by just one-hundredth of a second in the men's 100m.
Olympic finalist Ronnie Baker was third in 10.10 with Athens 2004 champion Justin Gatlin, now 39, fourth in 10.17.
Both Norman and Bracy were inside the previous meeting record of 10.03 set by Tokyo 2020 gold medallist Marcell Jacobs.
In the women's event, Richardson made good ground after a sluggish start but was just unable to go past Tokyo 2020 Olympian Oliver.
The 4x100m silver medallist crossed the line first in 11.19s with her compatriot awarded the same time in second and looking far from disappointed afterwards.
Jamaica's Olympic bronze medallist Ronald Levy took the men's 110m hurdles in 13.34.
In the women's pole vault, reigning world champion and Olympic silver medallist Anzhelika Sidorova came out on top with 4.70m before failing three times at 4.80m which would have broken her own meeting record.
The men's shot put did see a meeting record with American Josh Awotunde taking the win thanks to his throw of 22.00m in the final round.
He snatched victory from home thrower Zane Weir who also broke the previous mark and his personal best which placed him fifth in the Tokyo final with 21.63m.
