Seattle Mariners Preview
Seattle’s offense has been streaky this postseason. The Mariners are batting .207 through five playoff games with six home runs and 17 runs driven in. Cal Raleigh has been the most reliable hitter, going 8-for-21 (.381) with a homer and four RBI. Jorge Polanco has two home runs, while Julio RodrĂguez and J.P. Crawford have each added one.
Strikeouts have hurt Seattle’s run production, with 58 Ks through five games, but the starting rotation and bullpen have kept the Mariners in most games. The 15-inning win over Detroit showed how steady the relievers can be when games are on the line. Andrés Muñoz and Matt Brash have helped limit runs in key spots, giving the Mariners a chance even when the bats go cold. Seattle has not yet announced its starting pitcher for Game 1 on Sunday.
Toronto Blue Jays Preview
Toronto’s hitters have performed well at the plate during the postseason. The Blue Jays are batting .338 in four postseason games with nine home runs and 33 RBI.
