GMAT Sentence Correction (SC) | Re: The baseball All-Star Game signals the middle of the season

The baseball All-Star Game signals the middle of the season and reminds the losing teams that the time for them to improve their playing is running out.

C) The baseball season is divided in half by the All-Star Game

D) The All-Star Game signals the middle of the baseball season

I support A to be the correct answer D cannot be choosen just because of compactness because what if someone is not aware of baseball and its leagues and respective structure,
In plain grammer A is perfect and no reason to doubt it.
