Best Mariners vs. Blue Jays bets for Game 1 on Sunday

Seattle used a good chunk of its rotation in Game 5 to outlast Detroit, which means there might not be a lot left in the tank for top relievers in the later stages of Game 1 against Toronto. Bryce Miller (4-6, 5.68 ERA) is going to get the nod for Seattle in this contest. He’s been inconsistent to close out the season, allowing 16 runs over 25 2/3 innings in September. Miller pitched 4 2/3 innings against the Tigers in Game 4, giving up two runs and fanning two. The Blue Jays are going with Kevin Gausman (10-11, 3.59 ERA) for the series opener. He was excellent against the Yankees in his last appearance, allowing just one run over 5 2/3 innings.

The SportsLine Projection Model, which simulates every MLB game 10,000 times, has the Mariners covering +1.5 on the spread in over 70% of simulations, good for an ‘A’ grade.
