The Seattle Mariners will try to close out the Toronto Blue Jays in Game 6 of their American League Championship Series on Sunday at Rogers Center.

The Blue Jays are the betting favorites at home (–127), but the Mariners are coming off a potentially momentum-switching performance in Game 5.

Series Recap:

The Mariners became the first team to win at home in Game 5, thanks to three home runs, two of which came from third baseman Eugenio Suarez. Suarez put Seattle on the board with a solo blast in the second inning and then delivered a tie-breaking grand slam in the 8th inning. MVP contender Cal Raleigh also scored the home run that tied the match before Suarez hit the grand slam shot. Game 5 starters Bryce Miller and Kevin Gausmann canceled each other out as both pitchers allowed one earned run in this match.

Starting Pitchers Matchup:

Mariners RHP Logan Webb (1-0, 2.45 ERA): Webb is scheduled to hit the mound for the third time this postseason. The right-hander has allowed three earned runs over 9 innings this October, helping the Mariners win a couple of playoff games against the Tigers 8-4 on October 7 and the Blue Jays 10-3 on October 13. Webb is 3-0 in his last three starts against the Blue Jays, averaging 1.7 earned runs and 6.3 strikeouts in 5.0 innings per game.

Blue Jays RHP Trey Yesavage (1-1, 4.82 ERA): Yesavage looks to bounce back from a nightmarish stint on the mound last October 13, where he surrendered 5 earned runs over 4 innings in a 3-10 loss to the Mariners. Before Seattle exposed him in that forgettable Game 2, Yesavage was coming off a spectacular start against the Yankees on October 5, blanking the Bronx Bombers through 5.1 innings with 11 strikeouts.

Toronto Blue Jays - Seattle Mariners Key Points

  1. Seattle is 6-3 SU in its last 9 games.
  2. Seattle is 7-1 SU in its last 8 games on the road.
  3. Toronto is 1-5 SU in its last 6 games when playing at home against Seattle.
  4. Toronto is 9-4 SU in its last 13 games.

Our Toronto Blue Jays vs Seattle Mariners Prediction

Toronto is 1-5 SU in its last 6 games when playing at home against Seattle, while the Mariners are a fantastic road team this postseason with a 3-1 record away from home. Logan Webb has sported a 2.81 ERA in his last five starts, while the Mariners' bullpen has only allowed a 3.96 ERA in their last five games. I do not doubt that Yesavage will put up better numbers in his second postseason start against the Mariners. The problem is that Toronto’s relief pitchers are giving up a 6.88 ERA in the last five games. This could be problematic because the Mariners, like they showed in Game 5, are capable of turning the tide with their offense late in the game. Can Toronto extend this series to a winner-takes-all Game 7?

Fearless Forecast: The Mariners will wrap up this match 6-3 and advance to the World Series, where they will face the LA Dodgers. I feel Seattle will throw everything they’ve got in this match, knowing that playing the Blue Jays in Game 7 would be catastrophic to their chances of winning this series.

Our betting prediction for the Seattle Mariners vs. the Toronto Blue Jays: the Mariners will win.
