Elina Svitolina and Gael Monfils are ending their marriage. The sixth-ranked Ukrainian announced the split on Instagram Monday, calling it "the most difficult thing I have ever had to share."

The pair married in 2021 after dating for years on the professional tennis circuit. Both remain active competitors. Svitolina has won 18 WTA titles and reached career highs in the rankings. Monfils, a former top-10 player, continues competing on the ATP tour at 37 years old.

The announcement comes without details about custody of their children or the specifics driving the separation. Neither player has elaborated beyond Svitolina's initial post. Tennis divorces rarely dominate headlines the way athlete splits do in other sports, but when two ranked professionals part ways, it raises questions about scheduling and logistics on tour.

Both players now face the mental and logistical challenges of competing individually after years of supporting each other through injuries, tournaments, and travel. How this affects their on-court performances remains to be seen.
