With production being highly variable on a night-to-night basis, daily fantasy baseball plays a bit differently than other sports.
As a result of this, the primary method of selecting hitters is to "stack" certain teams in good spots to produce. Most of the top stacks on a given day come with hefty salaries.
In addition to that, a vast majority of pitchers with the upside to win tournaments are high-salaried. They don't allow many runs and strike opponents out often.
Therefore, crushing your value plays -- whether it be a pitcher unexpectedly piling up strikeouts or a lower-salaried batter racking up points -- is the true secret sauce to taking down a baseball tournament.
