The Canon EF 85mm f/1.2 L II Lens is not highly regarded for its autofocus speed, but it can work fine in some sports action photography. And the look this lens can create is matched by few other lenses - a relatively close perspective with a strong background blur. The subject will pop from the image.
Of course, keeping the thin f/1.2 DOF placed on your subject can be a challenge to both the photographer and the camera. Keeping the image dark enough is another challenge when shooting under full sunlight. Plan on needing 1/8000 and ISO 50 - or plan on using a neutral density filter.
