Why This Trend Exists

The Marlins' struggles as medium favorites stem from a fundamental organizational reality: they've rarely been good enough to warrant such confidence from oddsmakers. When Miami finds itself laying significant runs, it's typically due to facing weaker opponents or having a perceived pitching advantage that doesn't materialize consistently. The franchise's perpetual rebuilding cycles mean their roster depth is constantly in flux, making it difficult to capitalize on favorable matchups when the betting market expects dominance. Miami's ballpark factors compound these issues. Marlins Park's pitcher-friendly dimensions can mask offensive deficiencies during hot streaks, leading to inflated expectations when the team faces supposedly inferior competition. However, their inconsistent bullpen and tendency to struggle with situational hitting often prevent them from covering larger spreads, even against weaker opponents. The psychological element cannot be ignored either. Young Marlins teams often play tight when expectations rise, lacking the veteran leadership to handle pressure situations that medium favorite roles demand. Their offensive approach tends to be boom-or-bust, creating scenarios where they win games but fail to dominate as the run line suggests they should. This trend matters most when Miami faces rebuilding teams during interleague play, where unfamiliarity can level the competitive gap despite apparent talent disparities.
