What is the mistake in the phrase "the coach asked each player to get their soccer ball"?

The phrase "the coach asked each player to get their soccer ball" contains a grammatical issue related to subject-pronoun agreement. The term "each player" is a singular subject, referring to one player at a time. In standard English grammar, singular subjects should ideally take singular pronouns for clarity and agreement.

Therefore, "their," which is a plural pronoun, is inappropriate in this context. The correct pronoun to use would be "his or her" to maintain singular agreement with "each player." It's essential to ensure that pronouns match the number and gender of the nouns they replace to convey clear and precise meaning in writing.

Options pertaining to "each player," "to get," and "soccer ball" do not present the same grammatical issue, as they are used correctly in the context of the sentence.
