Moneyline/Runline: Toronto Blue Jays (ML/-1.5)

Entering into Game One of their three-game series, the Toronto Blue Jays open as the favourites to win the first meeting. During the regular season, the Mariners dominated the Jays, winning five of the seven games the two squads shared against each other. While the Mariners got the better of the Jays in these battles, we have Toronto getting the best of Seattle at home to kickstart their series.

The Blue Jays are the best hitting team in baseball, with a deep lineup filled with both powerful sluggers and solid on-base batters. The Mariners will have no room for mistakes as the Jays will make them pay top to bottom in their batting rotation.

In Game One, potential AL Cy Young candidate Alek Manoah will take the mound and look to bring his amazing regular season play with him into the playoffs. Manoah has been a consistent positive for the Blue Jays this season, playing sensationally and securing key victories for his team.

The Blue Jays will have home-field advantage throughout the Wild Card round which could benefit them greatly as they look to ride the momentum of their loyal fans to victory. Back the Blue Jays to start their playoffs off on the right foot and secure the win over the Mariners in Game One.

Over/Under: Under 7 Total Runs Scored

When looking at this matchup, the Under is a great bet to make on the Mariners VS Blue Jays Game One. With Playoff jitters expected to be a factor on both sides, it may take a few innings for either team to find their footing and start making connections with their bats.

For the Blue Jays especially they are a fairly young and inexperienced squad in terms of postseason play so it is likely they will need time to mentally adjust to the intense atmosphere of playoff baseball.

Another major factor to look out for in this game is the pitching from both teams. With each squad putting out their best pitchers, look for this game to stay low-scoring as they rely on the leaders of their bullpen to produce and keep their team within striking distance.

These two teams averaged seven total points scored in their seven matchups in the regular season, so this line will be riding razor thin towards being a PUSH.

Bet the Under on total runs scored in the Mariners VS Blue Jays Wild Card Game One.

Below you’ll find our top picks for player prop bets for Game One of the MLB Playoff Wild Card round between the Seattle Mariners and Toronto Blue Jays.

George Springer Over 0.5 Home Runs (+550)

A two-time Silver Slugger, and former-World Series MVP, George Springer was born to perform in when the light shine their brightest. A sensational playoff performer, Springer will be a leader in the Jays dugout in this opening round matchup, providing a boost both on the field as well as on the bench.

Springer has a history of blasting deep shots in the postseason so don’t expect this trend to stop anytime soon. Bet on Springer to hit a dinger in Game One of the 2022 Wild Card Round.

Alek Manoah Over 5.5 Strikeouts (-145)

As previously mentioned above, Alek Manoah is having an incredible season and all signs point towards this continuing into the MLB Playoffs. Manoah ranks 25th in the MLB in stirkeouts per nine innings played with 8.2. This demonstrates Manoah’s ability to put Ks up on the board as he throws ample heat over the plate.

Don’t miss out, bet on Alek Manoah to put on a clinic in his playoff debut and exceed 5.5 strikeouts in Game One against the Mariners.
