The Tampa Bay Rays are currently playing their best baseball of the season, riding a five-game winning streak that includes two decisive victories over the Mariners. Their strong home record (36-33) combined with their recent dominance over Seattle in Tampa (5-1 in their last six home meetings) provides a compelling case. While the Mariners are favored on the moneyline, the Rays' momentum, home-field advantage, and Adrian Houser's impressive 2.85 ERA offer significant value for an underdog pick.
