Melbourne, Australia (SportsNetwork.com) - Last year's runner-up Li Na and ninth-seeded German Angelique Kerber earned first-round wins Monday, while 2003 runner-up Venus Williams and seventh-seeded Italian Sara Errani suffered early exits at the Australian Open.

Kerber encountered a bit more resistance in her first-round matchup with Australia's Jarmila Gajdosova, but was able to bounce back from an ugly second set to claim a 6-3, 0-6, 6-2 victory.
Williams, meanwhile, jumped out to an early advantage against Ekaterina Makarova, but the seven-time major champion faltered down the stretch against the 22nd-seeded Russian, allowing Makarova to secure a 2-6, 6-4, 6-4 triumph.
