Gael Monfils and Elina Svitolina, two of the most accomplished players in tennis and one of the sport’s most prominent married couples, have taken out both of the world No. 4s on the same day, at the same event, in the same round—even on the same court. They both came back from a set down to do it, too.

Elina Svitolina said the supportive presence of husband Gael Monfils meant a lot after the tennis power couple made shockwaves in sync at the Australian Open on Saturday, knocking out the women's and men's fourth seeds as they both reached the last 16 of the singles.
