Victor Troicki has reached the third round of the Australian Open after defeating 26th seed Leonardo Mayer in four sets.
The Serbian, who missed last year's tournament due to a year-long ban for failing to produce a blood sample, progressed by a 6-4 4-6 6-4 6-0 scoreline.
Victory in Sydney at the start of 2015 has helped Troicki continue his rise back up the world rankings and another triumph on Wednesday against Mayer should see him move back into the world's top 50.
After the opening two sets were shared, Troicki edged out the Argentine in the third before coasting to the win with a 6-0 whitewash in the fourth set.
The 28-year-old will now play seventh seed Tomas Berdych for a place in the fourth round.
