curveball

Pitcher's deceptive throw

A curveball is a baseball pitch thrown with spin that causes it to curve as it approaches the batter, making it harder to hit.

The figurative meaning dominates everyday usage: an unexpected development that catches someone off guard.

Life threw me a curveball when I lost my job.

To throw someone a curveball is to surprise them with something difficult or unforeseen.
