Is this all correct where the commas are and am I using the right words?

1. Yes, Robin raced after a fly ball.
2. Cindy always worries about hitting the ball.
3. Alexis, Cindy, and Robin score runs every day.
4. Mark guesses we will win the tournament.
5. The race begins next week.
6. Wayne, Billy, and Travis plans to attend.
7. No, Charlene can't go.
8. She slipped on the stairs and broke her ankle.
9.She hopes she can go next time.

Everything is correct, except the verb in # 6.

planned to attend?

It should be

plan to attend

The subject is plural, so the verb also must be plural.

Thanks. Can you help me with these and see if they're correct?

10.Yesterday, the softball team arrived at the tournament.
11. Everyone carries her own glove, ball, and bat.
12. Well, the tournament begins right now.
13. Friends, parents, and grandparents fill the seats.
14. The team rushed onto the field.
15. Alexis pitched a fast ball.

All correct! Great!

Let's break it down and check each sentence for correct comma usage and word choice:

1. Yes, Robin raced after a fly ball.
- The comma is correctly placed to separate the interjection "Yes" from the rest of the sentence. The word choice seems fine.

2. Cindy always worries about hitting the ball.
- There are no commas required in this sentence. The word choice seems correct.

3. Alexis, Cindy, and Robin score runs every day.
- The comma is correctly used to separate the names in a list. The word choice seems correct.

4. Mark guesses we will win the tournament.
- There are no commas required in this sentence. However, the word choice may be improved by using "Mark guesses that we will win the tournament."

5. The race begins next week.
- There are no commas required in this sentence. The word choice seems correct.

6. Wayne, Billy, and Travis plans to attend.
- There should be a comma after "Travis" to separate the names in a list. The word choice seems fine, but the verb should be plural to match the subject. So, it should be "Wayne, Billy, and Travis plan to attend."

7. No, Charlene can't go.
- The comma is correctly used to separate the interjection "No" from the rest of the sentence. The word choice seems fine.

8. She slipped on the stairs and broke her ankle.
- There is no comma required in this sentence. The word choice seems correct.

9. She hopes she can go next time.
- There is no comma required in this sentence. The word choice seems correct.

To summarize, all the sentences are correctly punctuated except for sentence 6. The word choices in most sentences are also appropriate, except for sentence 4 where the word choice could be improved.
