Monday brought the turn of the men in getting their Brisbane International tournament underway, and even at this early stage of competition, the stars didn't fail to disappoint.
The Australian pair of Marinko Matosevic and James Duckworth had mixed luck at the first hurdle. The former triumphed over Julien Benneteau in three sets to earn his first victory in front of a home crowd, whereas Duckworth was soundly ousted from the running after falling to Jarrko Nieminen 6-2, 6-3.
Later on in the day, Sam Querrey managed to earn a memorable win over seventh seed Dmitry Tursunov, although it came close to the wire as both sets were decided by fine margins.
That wasn't long after Marin Colic got his tournament off to a bright start, coming from a set down to beat Denis Istomin 2-1 at the first obstacle.
Later on in the men's fixtures, Ryan Harrison suffered an early scare after losing his opening set against Tatsuma Ito.
However, the favourite rallied following the upset start to emerge as 2-1 victor, winning the second set 6-3 before demolishing the Japanese hopeful 6-0 ti finish with some flair.
Thanasi Kokkinakis and Yuichi Sugita had a far more rudimentary time in their opening fixtures. Kokkinakis conceded just five games in his two-set routing of Di Wu, while Sugita would defeat Pierre-Hugues Herbert 7-5, 7-6 to book a spot in the next round.
For the women, things got slightly tenser after Sunday's action was decided all too simply.
This time, Kaia Kanepit and Casey Dellacqua were made to fight for their progress, and each came out on top of three-set thrillers against Alexandra Panova and Galina Voskoboeva, respectively.
Britons will have been disappointed to see Heather Watson bow out of the competition at this early stage as she suffered a straight sets defeat against ninth-seed Dominika Cibulkova.
The world No. 121 made her opponent fight for the first set, but slipped to a disappointing 4-0 deficit in the second and was made to look out of her depth.
Elsewhere, Carla Suarez Navarro gave up just three games in her 6-2, 6-1 win over Su-Wei Hsieh, whereas world No. 47 Francesca Schiavone was handed her marching orders by fourth seed Jelena Jankovic, who strutted to a 6-2 opener before squeaking through thanks to a 7-6 win in the second set.
In her first match since suffering a shoulder injury in August, Maria Sharapova glided to a victory over Caroline Garcia in two quick sets. The Russian star needed just 64 minutes to dispose of her first opponent in nearly four months.
Sharapova's victory sets up a Davis vs. Goliath second-round matchup with 17-year-old Ashleigh Barty, who continued to roll with a victory over Daniela Hantuchova.
