Answer:
"but also struck out 10 batters"
Explanation:
The two which do not include "but" at the beginning don't flow with the way the rest of the sentence is structured. The "but also he made some some great catches" has two errors- the unnecessary repetition of the pronoun "he" and the repetition of the word "some".
Answer:
"but also struck out 10 batters."
Explanation:
Although the first option could work, this would be the best choice.
Choice #1= false because it uses "he" again.
Choice #2= false because when you're using "not only", you need "but also".
Choice #3= correct!
Choice #4= grammatically incorrect and does not include "but also"
