throw someone a curveball

Catch them off-guard

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

From baseball, where a curveball's deceptive trajectory makes it hard to hit: Life threw us a curveball when the company went bankrupt.

The phrase implies catching someone off guard, often with unwelcome complications.
