Explanation:
The first sentence talks about the narrator's approach to the plate and the second spoke of him hitting the ball.
If the writer were to put a sentence in-between those two, it would have to be something that happened between the approach and the first pitch. This is what option D does as it describes the atmosphere as the narrator approaches the plate.
It also adds the tension needed as it shows how much the narrator needs to do well.
