INDIAN WELLS, CA, USA - A decade ago, she was the women's singles champion, and former World No.2 Vera Zvonareva was back to her winning ways at the BNP Paribas Open on Monday.

The current World No.80 dispatched compatriot Irina Khromacheva in an all-Russian first round qualifying match at Indian Wells, 6-2, 6-3, as one of the biggest names in action on the first day.

The 34-year-old wasn't the only former Grand Slam finalist to win on Monday in the desert, as Italy's Sara Errani scored an upset over No.18 seed Heather Watson, 6-2, 6-7(3), 6-4, while former US Open semifinalist Yanina Wickmayer was also a winner, 6-2, 6-3 over No.12 seed Mandy Minella.

Top qualifying seed, Russian teenager Anastasia Potapova was among the upsets on day one, as she fell to Australia's Priscilla Hon, 6-7(3), 6-4, 6-0, in the first match on Stadium 4, and it was a sign of things to come for the afternoon. 

In all, eight seeded players fell at the first qualifying hurdle, including No.7 seed Lara Arruabarrena, who fell to rising talent and 2018 Wimbledon girls' singles champion Iga Swiatek of Poland, 6-1, 6-7(6), 6-2, and No.8 seed Kristyna Pliskova, who was beaten by 17-year-old American wildcard Catherine McNally, 2-6, 7-6(6), 7-5.

Switzerland's Viktorija Golubic continued her winning ways at Indian Wells - fresh off the WTA 125K title at the Indian Wells Tennis Garden on Sunday, the No.14 seed defeated Czech Republic's Marie Bouzkova, 7-6(5), 6-2, while No.19 seed Timea Bacsinszky topped Conny Perrin in a match of Golubic's compatriots, 5-7, 6-0, 6-1.
