An imperious Ashleigh Barty became the first Australian to win her home Grand Slam in 44 years Saturday, halting the charge of fearless American Danielle Collins in straight sets.
The world number one was 5-1 down in the second set but came storming back to win on a tiebreak and sweep past the 27th seed 6-3, 7-6 (7/2) to be crowned Australian Open champion.
