Questions & Answers about gataa kara booru ga booruritaan ni modoru.
から marks the starting point or source of movement. In this sentence, the ball starts in the gutter, so ガターから means from the gutter.
A useful pattern is:
A から B に 戻る
= return from A to B
So here:
ガターから ボールリターンに 戻る
= return from the gutter to the ball return
が marks ボール as the subject of the verb 戻る.
In other words, the ball is the thing that performs the action of returning:
ボールが 戻る
= the ball returns
A learner might expect は instead, and は is also possible in some contexts, but it changes the feel a bit:
- ボールが戻る: focuses on the ball as the thing that returns
- ボールは戻る: presents the ball as the topic, something like as for the ball, it returns
In a simple descriptive sentence like this, が is very natural.
