Maddison Keys ends Samantha Stosur's Brisbane run
Samantha Stosur's bright start to the summer has been halted by the power of Madison Keys in a 7-5 6-3 second-round loss in the Brisbane International.
Local hope Stosur had upset former world No.1 Angelique Kerber to progress beyond the first round for just the second time in seven years on Monday.
And the veteran started well against the eighth seed and 2017 US Open finalist by grabbing an early break on Wednesday.
But the American responded with a break of her own, and applied the pressure again in the 12th game to seal the first set.

Keys broke serve again to begin the second before, behind 10 aces, going on to seal victory in 77 minutes.
Former US Open champion Stosur will continue her Australian Open preparation at the Hobart International.
It was the third American success on Wednesday after Alison Riske beat Barbora Strycova 6-3 6-4 and Danielle Collins trounced Yulia Putintseva 6-1 6-0.
Australian world No.1 Ashleigh Barty won't begin her singles campaign until Thursday but is already just one win from the doubles final.
Barty combined with Dutch talent Kiki Bertens to beat second seeds Nicole Melichar and Yifan Xu 6-3 6-2 in less than an hour on Wednesday.
The 23-year-old will play Jennifer Brady in the second round on Thursday.
