Best MLB bets for Wednesday, Oct. 15

The Mariners are turning to George Kirby (10-8, 4.21 ERA) for Game 3. Kirby is coming off a strong outing in Game 5 of the ALDS against the Tigers, where he allowed just one run in five innings. Seattle has been getting strong production from Cal Raleigh, Josh Naylor and Jorge Polanco so far in the playoffs, with Polanco actually leading the team in home runs and RBI. On the flip side, the Blue Jays have cooled off substantially after putting up 34 runs across four games in the ALDS against the Yankees. Toronto is hitting .131 as a team over the first two games of the ALCS. The hope is Shane Bieber (4-2, 3.57 ERA) can deliver a good pitching performance in Game 3. Bieber was rocked in his last appearance, giving up three runs in 2 2/3 innings in Game 3 of the ALDS against New York. The SportsLine Projection Model likes the Mariners to take Game 3, as they win in 61% of simulations as -130 favorites (wager $130 to win $100).

Responsible gaming

Responsible gaming is important at all sportsbooks, which provide tools like setting deposit limits and using self-exclusion measures for all users.

All sportsbooks have contact information for helplines and other resources on their platforms for users who require more assistance.
