Morphology

stay + on + the + ball

The sense 'remain alert' is based on a sports metaphor ('on the ball') rather than a literal combination of 'stay' + 'on' + 'ball', so a B1 learner who only knows the constituent words is unlikely to derive the idiomatic meaning reliably. There is some partial transparency because the locative pattern and the sporting image (being 'on' a ball = ready/engaged) can cue attentiveness, but the specific idiomatic extension requires exposure.

Etymology

The idiom stay on the ball comes from sports where players must keep their eyes on the ball and be ready to move. If you actually 'stay on the ball' you can act fast, so the phrase now means 'to remain alert and ready to act'.
