Iga Swiatek may not love the grass but relishes a battle whatever the surface and showed all that fight and bullish determination as she recovered to beat American Caty McNally 5-7, 6-2, 6-1 and reach the Wimbledon third round on Thursday.

Iga Swiatek didn't have an easy day at the office and came a set away from suffering another early Wimbledon exit before storming back to beat world No. 208 Caty McNally 5-7 6-2 6-1 in just less than two and a half hours of play.

Chaos reigned during the first three days at Wimbledon, with half of the women's Top 10 seeds ousted, before order was restored Thursday in London. Seventh-seeded Mirra Andreeva of Russia and eighth-seeded Iga Swiatek of Poland both prevailed on the grass courts to forge ahead to the third round.
