Players bite into Vegemite challenge

For a little healthy fun off the courts, a group of players at the Australian Open took part in a Vegemite taste test.

For Australians, it is the country's signature spread, a beloved national snack typically slathered on toast. It is to Australians what peanut butter is to Americans, or Nutella to the French.

Australia's Sam Groth, one of a dozen players who joined a video challenge put online by the ATP, took one smell and licked his lips.
