Andre De Grasse helps Canada's relay team to world-leading 4x100
Quartet win double gold at Florida Relays on Saturday
Canada's Andre De Grasse is back in action for the first time since winning three medals at the Rio Olympics.
On Saturday, De Grasse ran legs in both the 4x100-metre and 4x200 at the Florida Relays in Gainseville, Fla.
Alongside Canadian teammates Akeem Haynes, Aaron Brown and Brendon Rodney, they ran a world-leading 38.15 seconds to claim gold in the 4x100. Gavin Smellie filled in for Haynes in the 4x200, which the Canadians won in 1:19.91.
De Grasse is expected to be a part of Canada's team at the upcoming 2017 IAAF World Relays in Nassau, Bahamas from April 22-23.
The men's team is coming off a bronze-medal performance at the 2016 Rio Olympics in the 4x100.
