Canada's junior women/mixed relay teams are too classy for the rest of the field, really wish China had brought their best so there could be some proper battles in those events. Even our guy Gaziev smashed his 50.66 PB to 50.32 leadoff in mixed relay heats and now 49.99 leadoff in mixed relay final. And Alex Pratt has a 51.87 PB (he's more of a distance man) and put up two sub 51 laps in heats and finals. Really looking forward to Women's 4x100m where Sanchez (3rd in individual), Smith (4th in individual), Ruck, and Oleksiak should go after another WJR
