Commas are needed for non-essential clauses (before and after), but not for essential clauses.

To determine if a phrase is essential or nonessential in a sentence, you need to assess whether removing the phrase would significantly alter the meaning or clarity of the sentence.

Now, let's analyze each sentence and label if the phrases are essential or nonessential:

1. "Mickey was named after the catcher Mickey Cochrane who made it into the Hall of Fame."

In this sentence, the phrase "who made it into the Hall of Fame" provides additional information about the catcher named Mickey Cochrane. If this phrase is removed, it would not change the meaning of the sentence. Therefore, it is a nonessential phrase.

2. "Mantle's father, who worked in the lead mines, had played semi-pro ball."

In this sentence, the phrase "who worked in the lead mines" provides additional information about Mantle's father. Removing this phrase would not significantly change the meaning of the sentence. However, if you choose to keep it, you should use commas to set off the nonessential phrase "who worked in the lead mines."

3. "Mantle, who was named the Most Valuable Player three times, also played in 16 All-Star games."

In this sentence, the phrase "who was named the Most Valuable Player three times" provides essential information about Mantle. Removing this phrase would change the meaning of the sentence, as it highlights an important aspect of Mantle's achievements. Therefore, it is an essential phrase.

So, to summarize:

1. Nonessential phrase (no comma needed)
2. Nonessential phrase (comma needed)
3. Essential phrase (no comma needed)

Please note that while certain phrases are typically considered essential or nonessential, context and personal style can sometimes influence the classification.
