TOKYO :The United States finished the world championships in style as Noah Lyles and Melissa Jefferson-Wooden completed memorable individual weeks by helping their country to emphatic golds in both 4x100 metre relays in driving rain on Sunday.

Jefferson-Wooden became the second woman to sweep all three sprint titles at one World Athletics Championships.

The 24-year-old, who won the 100-200m double in Tokyo, helped the United States to a lead at the last exchange and Sha'Carri Richardson brought the baton home in 41.75 seconds.

Jamaica finished second in 41.79 to send sprint queen Shelly-Ann Fraser-Pryce, whose 2013 sweep Jefferson-Wooden emulated, into retirement with a 17th world championship medal.
