She played basketball.
Literal
She [topic-は] basketball [object-を] did.
About as compact as Japanese predication gets. The structure ~をする ('do X') is the workhorse for turning an activity noun into a verb — テニスをする, 勉強をする, 散歩をする — and works equally for sports, study, and casual activities alike. With sports specifically, you can also drop the を in casual speech (バスケする) when the noun and the verb are felt as one unit.
