There are a number of ways of dealing with unwanted visitors during a tennis match. In Hua Hin, Sabine Lisicki was attempting to remove an insect from the baseline during her first-round contest with Garbine Muguruza. The 29-year-old German was going for a distant and gentle approach when a ball girl stepped in—literally.

The ruthless move shocked Lisicki, who would go on to lose the match, 6-3, 6-4. Muguruza is the top seed at the International event.
