Seattle Mariners play in the AL West.

Seattle Mariners overview

The Seattle Mariners play in the American League West at T-Mobile Park, known as Safeco Field until 2019. Founded in 1977, the Mariners are the only active MLB franchise that has never appeared in a World Series, despite stars such as Ken Griffey Jr., Edgar Martinez, Ichiro Suzuki and Randy Johnson. Seattle's 2001 team tied the major league record with 116 wins. For bettors, T-Mobile Park is one of the most pitcher-friendly parks in baseball, and the Mariners' geographic isolation means they log more travel miles than almost any other team, which can matter on long road trips and in scheduling spots.

Betting insights

T-Mobile Park has consistently ranked among the toughest places to score in MLB. The cool, damp Pacific Northwest air suppresses fly balls, especially at night, and the retractable roof only covers the field rather than enclosing it, so conditions remain cool even when it is closed. Seattle home totals are frequently low for good reason, and bettors should focus on whether the number is low enough. Seattle teams have often been built around starting pitching, which makes first five innings bets and unders worth considering in the right matchups. The Mariners' long travel schedule creates spots such as the first game home after an East Coast trip.
