on the ball
Quick and attentive
On the ball means alert, quick to understand, and competent—performing at a high level of awareness and efficiency.
Someone on the ball catches problems early, responds quickly, and stays ahead of tasks: She's really on the ball—she noticed the error before anyone else did.
The phrase likely derives from sports, where keeping your eye on the ball is essential to good play.
