Dangling Modifiers:
Modifiers are used by writers to give a clear and logical meaning to sentences.
The above sentence fails to give a clear meaning to who made the team and lost a lot of free time. It sounds vague. - That is why it´s known as a dangling modifier because the word which gives a clearer meaning is missing (dangling).
To understand better the meaning of the sentence, it could read: After Joy made the team, practices and games took up a lot of her free time.
OR
After making the team, Joy´s practices and games took up a lot of her free time.
