Venus Williams remained winless on the year after dropping her first-round match to Australia's Ajla Tomljanovic 6-4, 6-1 on Tuesday at the ATX Open in Austin, Texas.

Williams, 45, is 0-4 for the season, including a loss to Serbia's Olga Danilovic at the Australian Open last month. The seven-time major champion has lost seven singles matches in a row dating back to defeats last summer in Cincinnati and then at the U.S. Open against the Czech Republic's Karolina Muchova.

The Tuesday match featured seven service breaks, five by Tomljanovic, who lost three of the first four games before dominating the rest.

The day's action saw two seeded players fall. Ashlyn Krueger defeated seventh-seeded Caty McNally 6-1, 7-6 (5) in an all-U.S. matchup, and Australia's Kimberly Birrell rallied past eighth-seeded Croatian Petra Marcinko 0-6, 6-3, 6-4.

Second-seeded Iva Jovic of the U.S. ousted Russia's Anna Blinkova 6-3, 6-4, and the United States' Peyton Stearns overtook Great Britain's Francesca Jones 3-6, 6-3, 6-2. Also advancing were Russia's Anastasia Zakharova, China's Yue Yuan, Hungary's Dalma Galfi, Slovenia's Kaja Juvan and the United States' Caroline Dolehide.
