Noah Lyles won his third world gold of the championships in Budapest after anchoring the US team to victory in the 4x100m relay on Saturday.
After claiming a first individual sprint double since Usain Bolt in 2015, Lyles mirrored the Jamaican legend in running the fourth leg to help take his team to the win in 37.38 seconds.
Olympic champions Italy, with Tokyo 100m gold medallist Marcell Jacobs on the second leg, claimed silver in 37.62sec, while Jamaica took bronze (37.76).
Christian Coleman, the 2019 world 100m champion, led the US quartet off, handing over to last year's 100m champion Fred Kerley.
Kerley's baton exchange with third leg Brandon Carnes was almost botched, but the latter regained his rhythm and rounded the final bend for a perfect lay-off to Lyles.
The 26-year-old scorched down the home straight, crossing the line with three fingers raised to signify his three medals he'll take home from the championships in the Hungarian capital.
