Baseball and softball are two rather straight forward sports to cover. There is some added information needed depending on the level of play being covered.
Simple notes are done usually in a play by play type so that facts are straight as to how the runs are scored throughout the game and also can key in on big moments of the game, such as a home run or a diving catch.
Interviews necessary are coaches and some players that were key in the game as you see fit.
Added things to know for higher level baseball, such as American Legion or high school level are winning and losing pitchers, home runs hit, a linescore for runs, hits, errors, and all the other pitchers that play and what inning they enter the game.
