Marlins vs Guardians Preview, Picks
When the Marlins open a series against a team coming off a game in the Eastern or Central time zone, the market often underrates the visiting team due to the perception of minimal travel impact, which appears to be the situation entering tonight’s matchup against the Guardians.
In reality, these teams enter Game One with their routines intact and without the challenges of cross-country adjustments, allowing them to perform at expected or elevated levels.
Because the Marlins are not typically priced as a top-tier opponent, this creates value in fading them in the series opener.
This system capitalizes on that edge by betting against the Marlins in Game One during the regular or postseason when their opponent’s previous game was played in the Eastern or Central time zone, turning overlooked market assumptions into a profitable opportunity.
