Zmarzlik and Kurtz level on points — Latvia GP becomes the season's key round

Bartosz Zmarzlik is chasing a seventh individual speedway world title and is level on points with Australian Brady Kurtz heading into the Latvian Grand Prix. Saturday's round has become the most important of the season — made more significant by the fact that Zmarzlik lost to Kurtz on the same track last year. Three rounds remain in the series.
