A person is posed with one leg raised and one arm out at a competition with their teammates in the background.
A man posed at a baseball game.
A person doesn't necessarily have to be a man, and there are a number of competitions with teammates that are not baseball.
Just becuase the man is posing with his teammates does not mean he is at a baseball game.
Just because the person is a part of a team does not mean he is on a baseball team or at a game.
