Mariners at Blue Jays picks and predictions

Prediction

Blue Jays 4, Mariners 3

Moneyline

BET BLUE JAYS (-118).

The Blue Jays were 43-38 at home a season ago, and they should get a boost with this being their home opener. Toronto has lost 2 in a row, but has scored 11 runs over its last 2 games.

Berrios has been terrific to start the season, and the Blue Jays have won 8-2 and 2-1 in his 2 starts. The Mariners have lost 4 of their last 5 and have allowed at least 5 runs in both Games which Castillo started.

Considering those trends, take BLUE JAYS (-118).

Run line/Against the spread

PASS.

There’s no value in taking the Mariners -1.5 (+158), who have been an underdog in all but 1 game, as a run-line favorite. Similarly, the Blue Jays +1.5 (-192) are too expensive on the run line to play here.

Over/Under

LEAN UNDER 8 (-104).

The Blue Jays might be 6-3 O/U on the season, but they have allowed just 3 runs in the 2 Games that Berrios has started. They have also gone Under in 2 of their last 4 Games.

While the opposite of that success can be said for Castillo, he is still among the premier pitchers in the game and should be able to figure things out. The Mariners are 5-4-1 O/U this season but have yet to score more than 5 in a game. They have scored 2 or fewer in 4 of their last 9.

Considering the trends for both pitchers, take UNDER 8 (-104).
