The Toronto Blue Jays and Seattle Mariners have consistently exceeded the projected run total in recent matchups. Their last three games have all gone over the total, illustrating both teams’ offensive capabilities.

The Blue Jays’ postseason form at the plate, led by standout performances from Vladimir Guerrero Jr. and Ernie Clement, suggests a continued offensive output. Meanwhile, the Mariners have shown they can keep pace, ensuring a high-scoring affair.

Starting pitchers George Kirby and Shane Bieber have respectable stats, but the offensive prowess of both lineups, particularly in the postseason, indicates an edge towards scoring. Additionally, the Mariners’ road struggles might contribute to more scoring opportunities for the Blue Jays.

With the over trend being dominant in their recent meetings and postseason performance, expecting a game total surpassing 7.5 runs is reasonable. The Blue Jays’ recent 6-2 win further supports an expectation for a higher scoring Game 7.
