World number one Ash Barty doled out the dreaded 'double bagel' to Danka Kovinic in the first round of the Australian Open on Tuesday, humiliating the error-prone Montenegrin 6-0 6-0 on Rod Laver Arena. Barty, looking to become the first homegrown champion at the Grand Slam since 1978, won the first 16 points of the one-sided contest and never looked back, wrapping up the win in 44 minutes. Next up for Barty is a second-round match against Spain's Sara Sorribes Tormo or local wildcard Daria Gavrilova.
